Colchester United 1-4 Tottenham Hotspur: FA Cup fourth round as it happened

A dominant performance from Tottenham as they breeze through to round five. Even though Colchester kept things close for the first hour or so, the gulf in class between the two teams was obvious throughout and losing both centre-backs to injury so early certainly disrupted Keen's plans.

That is it for this particular blog, but click here to follow live coverage of Arsenal vs Burnley and the rest of the 15.00 kick-offs. We will also have Liverpool vs West Ham for you later on this afternoon.

Full-time

Colchester 1-4 Tottenham

Two minutes of additional time signalled at the end of the second half. A comfortable afternoon's work for Tottenham, who have really exercised their dominance since the break.

A flurry of late goals in this one as Tottenham restore their three-goal lead. Carroll is the man who scores, knocking the ball to Chadli before running unmarked into the six-yard box and flicking cleverly past Kean.

Two goals in quick succession as Chadli nips in ahead of Kent at the near post to head Trippier's cross beyond Kean.

Colchester then launch an attack of their own and Moncur tees up Massey, whose shot with the outside of his boot comes back off the post and hits Davies before crossing the line.

Goal: Colchester 0-3 Tottenham (Nacer Chadli)

Brindley shoots just over for the hosts before Sordell is sent clean through and looks certain to score before sliding a low shot agonisingly wide of Vorm's left-hand post.

Pochettino makes his last change, replacing Eriksen with 18-year-old Josh Onomah.

Kane's afternoon draws to a close as the stand-in captain is replaced by Son. Dembele will take over as skipper for the final 20 minutes.

After spurning a number of good opportunities to double their lead, Tottenham finally do so as Dier picks up the ball from distance and hits a hopeful shot that takes a massive deflection off Briggs and wrong foots Kean before bouncing into the net.

Lady Luck has really not been smiling upon Colchester this afternoon.

Goal: Colchester 0-2 Tottenham (Eric Dier)

A final change from Colchester sees Sordell replace Ambrose.

How are Tottenham not 2-0 ahead? Kane tees up Chadli, who takes a touch and turns before crashing an effort off the crossbar from close range. He definitely should have scored that.

Colchester appeal in vain for a penalty after Wimmer wins the ball with a lunging challenge on Porter but leaves his leg dangling and invites the striker to take a tumble. Referee Oliver is unmoved.

Colchester are growing in confidence as Ambrose breaks down the right and produces a pacey cross towards Porter, but the home skipper is just unable to make contact.

Pochettino then makes his first change of the afternoon, with Dembele on for Lamela.

Encouraging persistence from Moncur as he does well to keep Owen Garvan's pass from trickling out of play before laying in a low ball for Ambrose, whose shot is deflected wide by Bentaleb.

From the resulting corner, the ball breaks for Gavin Massey who fizzes a low shot that is held by Vorm.

A busy start to the second half for Lamela as he receives possession from Eriksen and rather than returning the favour, cuts inside and pulls a low shot wide.

Briggs loses possession in his own half and Kane edges forward before lofting a ball into the path of Lamela, who takes a touch on his chest before prodding inches wide of the far post. That should have been 2-0.

Both teams have re-emerged from the tunnel and the second half is now underway. No changes from either side at the break. Keen has only one substitution remaining of course.

A deserved lead for Tottenham at the break, but Colchester have fought valiantly when you consider that they lost both of their starting centre-backs within the first 20 minutes.

It was a peach of a strike from Chadli to give the visitors the lead and although Keen's side have yet to provide much of a sustained attacking threat, they will take great encouragement from only being 1-0 down.

Half-time

Colchester 0-1 Tottenham

Wild from Bentaleb as he lashes over from distance. That should be it for the first half.

More danger for Colchester as Kane charges forward and looks to take on Kent one-on-one but the young substitute watches the ball all the way before winning it with a firm challenge. Impressive defending from the 20-year-old.

Eriksen picks out the run of Trippier, who powers an excellent low cross beyond Kent that skips up and bobbles off Kane's knee in a good position. His blushes are spared as the offside flag is belatedly raised.

The fourth official's board shows six minutes of added time at the end of this opening 45.

A chance for Colchester to put a decent ball into the box after a foul from Carroll ends tamely as a long-range header from Alex Gilbey is easily scooped up by Vorm. Two minutes of the first half remaining, although there is likely to be a lot of stoppage time following that collision between Wynter and Eastman.

That was uncertain from Kean as he palms behind a looping Bentaleb cross from the right that looked to be drifting harmlessly wide.

Another delivery from Trippier is then headed away by Briggs and Carroll turns the loose ball well over.

The Us are beginning to come into this match a little more as Ambrose sees a long-range shot blocked and Dier, reverting to centre-back today after playing much of the season as a holding midfielder, has to be alert once more to head behind Brindley's cross.

Two chances for Kane as he first ignores an incisive run from Lamela before lashing into the side netting from a difficult angle.

The England striker then gets involved in a slick passing move with Eriksen and Davies before heading the latter's inch-perfect cross straight at Kean from close range.

A rare foray forward from Colchester as Carroll gives the ball away in a dangerous area. Ambrose then finds George Moncur, but his shot is blocked by Dier.

Just moments after Eriksen shoots narrowly over on the break, Colchester's resistance is finally broken. Following a quick passing move in midfield, Lamela finds Chadli with the outside of his boot.

The Belgian, who has scored in each of his last two games, takes one touch before rifling home an impressive shot that appeared to swerve on its way into the back of the net.

Goal: Colchester 0-1 Tottenham (Nacer Chadli)

Trippier is now down receiving treatment but it looks like he will be fine to continue. Still goalless after 25 minutes, which will surely please Keen given how unlucky they have been with injuries.

Relief for Vorm as he races out to collect a lofted ball towards the run of Porter and comes within a whisker of handling the ball outside his penalty area. The home fans appeal, but it looked like he just let go in time.

A second enforced defensive change from Keen inside the first 20 minutes as Briggs replaces Eastman, who had done well since coming back on but will not continue following that hefty blow to the head.

That is both Colchester centre-backs lost now.

Committed defending from Eastman to block two efforts from Eriksen in quick succession. Lamela bends a corner to the back post but Chadli's header is mistimed and goes well wide.

Trippier has enjoyed a lot of success down the right-hand side in this opening 15 minutes. The former Burnley full-back is rewarded for his persistence as he beats Ambrose and sends in an inviting low cross that Kane, darting to the front post, flicks into the side netting.

So close to the opening goal as Bentaleb finds Lamela in acres of space and the Argentine unleashes a whipped left-footed effort that beats Kean before smacking against the post.

Eastman has finally returned sporting a thick bandage around his head.

The visitors come forward once again as they look to make the most of their one-man advantage. Chadli has a low shot saved by Kean. Colchester need to get Eastman back on the pitch as soon as possible or else they may be forced into a second substitution.

Good pressure from Tottenham as Trippier rampages down the right once again before providing a dangerous low cross that Richard Brindley does well to clear off the toes of Chadli.

The attack stays alive and Eriksen tries to find Kane before lashing a powerful shot that is well parried by Kean.

A hearty round of applause from the home supporters as Wynter is stretchered off with what looks like a bad head injury. Frankie Kent replaces him, but Colchester remain down to 10 men with Eastman still receiving treatment.

That was a sickening clash of heads as the two centre-backs tried to snuff out a ball over the top towards Kane. Eastman has gone down the tunnel to receive treatment for a head wound, while Wynter remains laid out in worrying scenes on the pitch.

There will definitely have to be an early change from Keen.

A lengthy stoppage now following a nasty collision between Colchester defenders Alex Wynter and Tom Eastman.

Almost an early opportunity for Chadli as Kieran Trippier gets the better of Vincent-Young down the Tottenham right and produces a cross that bounces off the Belgian's head and into the hands of goalkeeper Jake Kean.

Referee Michael Oliver gets the match underway. Can Colchester spring a surprise here?

More on that proposed Dembele deal as the teams emerge from the tunnel...

Under five minutes remaining until kick-off now. Tottenham, who are generally impressive away from home, have not reached the fifth round of the FA Cup since 2012, while Colchester last did it a decade ago.

With deadline day fast approaching, there has been transfer talk surrounding both of these teams before kick-off this morning.

Not merely content with possessing just one Mousa Dembele, reports suggest that Tottenham are closing in on a deal for his namesake at Fulham. The 19-year-old French forward is believed to be undergoing a medical today but is expected to return to Craven Cottage for the rest of the season.

On the bench for Colchester today meanwhile is Macauley Bonne. Joint-top scorer in the FA Cup this season thanks to his four-goal haul in the 6-2 demolition of Wealdstone, the former Ipswich trainee is said to be attracting attention from around the Football League.

Colchester have now moved to clarify an earlier mistake that suggested Sordell had been selected ahead of captain Chris Porter up front...

Seven changes in total for Tottenham today, but they have still managed to field a strong side that you imagine should be well capable of avoiding any shock upset.

Clinton Njie would likely have been involved if he were not still recovering from surgery on a knee injury sustained against Monaco in December. Midfielders Ryan Mason and Alex Pritchard remain absent with ankle trouble, but Pochettino confirmed in his pre-match press conference that both players should return to training very soon.

There is no George Elokobi for Colchester today despite the powerful defender returning to fitness after a hamstring problem. New signing Nicky Shorey also misses out, but 19-year-old Kane Vincent-Young replaces Matthew Briggs following the 3-0 defeat to managerless Scunthorpe.

Gavin Massey is in for Joe Edwards and the experienced Darren Ambrose starts ahead of Marvin Sordell, who drops to the bench.

Colchester: Kean, Brindley, Wynter, Eastman, Vincent-Young, Massey, Gilbey, Garvan, Ambrose, Moncur, Porter (c)

Substitutes: Parish, Edwards, Lee, Bonne, Sordell, Kent, Briggs

Plenty of alterations as expected for Spurs. Michel Vorm deputises for Hugo Lloris in goal, while Kevin Wimmer is paired alongside Eric Dier at centre-back with Toby Alderweireld rested and Jan Vertonghen sidelined after sustaining knee ligament damage during the 3-1 win at Crystal Palace last weekend.

Ben Davies is in for Danny Rose at left-back and Tom Carroll is paired with Nabil Bentaleb in midfield. Christian Eriksen and Harry Kane keep their places, but Erik Lamela and Nacer Chadli replace Son and the in-form Dele Alli.

Tottenham: Vorm, Trippier, Dier, Wimmer, Davies, Bentaleb, Carroll, Lamela, Eriksen, Chadli, Kane (c)

Substitutes: Lloris, Alderweireld, Walker, Alli, Dembele, Onomah, Son

Team news to come shortly...

With a sizable squad at his disposal, Pochettino has already confirmed that he will make changes for today's cup tie. He did the same in round three, when Tottenham needed a controversial late Harry Kane penalty to force a replay against Leicester. They won the return fixture 2-0 courtesy of goals from Son Heung-Min and Nacer Chadli.

Colchester boss Kevin Keen, a former assistant to Steve Clarke at West Brom and Reading who succeeded Tony Humes in December, does not have the same luxury, however.

The visitors are enjoying an impressive second season under the management of Mauricio Pochettino. Currently sitting fourth in the Premier League with just three defeats since August, Tottenham are also in Europa League last 32 action against Fiorentina next month.

As for Colchester, their perennial struggle to stay afloat in the third tier looks like it might be just too much of a stretch this season. Rock bottom of League One and seven points adrift of safety, their third-round triumph over troubled Championship outfit Charlton was their only win in any competition since December.

In fact, if you take out earlier FA Cup victories over non-league opposition in Wealdstone and Altrincham, The Us have not tasted victory since beating Port Vale on 20 October. Grim.
