4pm: Chelsea vs Manchester City
Full time: Chelsea 5-1 Manchester City
Manuel Pellegrini's experiment backfires as Chelsea cruise into the last eight of the FA Cup. Manchester City handed full debuts to seven youngsters and they were given a harrowing insight into life at the top level with a heavy defeat. Guus Hiddink remains on course to win the trophy for a second time.
Well that is all we have time for on this live blog. We have live coverage of the sixth round draw on the way but until next time, goodbye.
Goal: Chelsea 5-1 Manchester City (Bertrand Traore)
Cherry on the icing on the top of the cake. Bertrand Traore flicks on an Oscar cross and it loops into the air and in off the post. Cabellero hopeless.
City not going down without a fight and Kolarov forces Courtois into a good low save. Into the last couple of minutes.
Traore hits the post after another Hazard assist. Much improved from the Belgian.
Willy Cabllero keeps out Oscar's penalty. It was a stuttering run-up and the Brazilian hit it at a nice height before seeing the effort beaten away. Justice perhaps done with Demichelis' nudge on Traore hardly worthy of a spot-kick.
Penalty to Chelsea
Quick update on the incident which saw a stream of coins launched in the direction of Manchester City's players after they scored in the first half; Chelsea have promised to ban those offending fans for life if and when they are found.
Iheanacho tries to get one back with a cute backheel but a combination of Ivanovic and Courtois keep it out. Diego Costa off for the final quarter of the game, such is the comfort of Chelsea's position.
Goal: Chelsea 4-1 Manchester City (Eden Hazard)
In a season of few highlights, that has to be Eden Hazard's stand-out moment of the season. The Belgian takes aim from a 20-yard free-kick, that he won after being cut down by Demichelis, and he sends Caballero the wrong way and finds the corner. Game over now.
The hosts are toying with their opponents now and they almost cruise to a fourth as Costa and Hazard combine, but Fabregas can only shoot wide. City may have nearly half an hour left but they look spent to me.
Chelsea threatening to pull away from City now and Willian plays in Pedro, whose cross-shot is turned behind by Demichelis.
Goal: Chelsea 3-1 Manchester City (Gary Cahill)
That might be that for City's youngsters. Two goals within eight second half minutes put Chelsea in complete control. Hazard's cross is only half cleared by Fernando, allowing Cahill to slam home. Caballero culpable again.
Goal: Chelsea 2-1 Manchester City (Willian)
Within three minutes of the restart Chelsea are back in front. Willian exchanges passes with Hazard and converts with aplomb. Fine goal from the Blues' best player of the season.
Players are out and we're back under way at Stamford Bridge. No changes at the break.
Half time: Chelsea 1-1 Manchester City
Very satisfactory half for Manchester City. Their young players have more than held their own and though they could have gone under after Diego Costa's opener but they levelled straight away through David Faupala. Manuel Pellegrini will likely emerge from this game with some credit, after all.
Chris Brunt, the West Brom captain, had a coin throw at him by his own supporters following the loss to Reading yesterday and I am sorry to report we have had a repeat of those scenes at Stamford Bridge. City players has several coins thrown at them by Chelsea supporters as they celebrated equalising. Referee Andre Marriner saw the incident and picked up some of the offending items. Not the last we will hear of that I would think.
Goal: Chelsea 1-1 Manchester City (David Faupala)
Manchester City bite back straight away and it is a debut goal for David Faupala. Garcia and Iheanacho combine and when Azpilicueta messes up his clearance Faupala is on hand to poke home.
Goal: Chelsea 1-0 Manchester City (Diego Costa)
The Blues ahead with the easiest goal they will sore all season. Fabregas lifts the ball over the defence for Hazard whose cross is headed in by the unmarked Diego Costa. But...
City have not been the cannon fodder many might have expected this afternoon and Iheanacho shoots from range on the break but is balloons over the bar.
Tosin Adarabioyo has the daunting task of marking Diego Costa this afternoon but he has started well, keeping the Spain striker at bay when he looked set to go through on goal. Keep an eye on that rivalry at the game goes on.
First effort in anger from Chelsea and they almost take the lead. Pedro exchanges passes with fellow-Spaniard Cesc Fabregas and lifts the ball over Caballero but only hits the post.
Gary Cahill down with what looks like a calf or hamstring problem. Matt Miazga warms up hopefully.
First look at Faupala, who leads the City attack this afternoon. He goes past two Chelsea challenges and forces the first save of the afternoon out of Courtois, who pushes away his goal-bound effort.
Underway at Stamford Bridge. Manchester City in their 'ghost green' kit. Whatever that means.
