3pm: Tottenham Hotspur vs Crystal Palace
Full time: Tottenham 0-1 Crystal Palace
All over at White Hart Lane and a shock of sorts as Crystal Palace knock out Tottenham. Martin Kelly puts the Eagles into the last eight for the first time in 21 years with a fine first half strike. Spurs threatened in dispatches but could not find their way past a stubborn Palace defence. They go into the hat for the quarter-finals.
Well that is all we have time for on this live blog. You can follow the second half of Chelsea vs Manchester City here, but until next time goodbye.
Into three minutes of stoppage time at White Hart Lane and Tottenham are not showing any signs they are on the verge of a late equaliser. Palace have been the more threatening of the two sides in the close minutes.
Ball in the net but it has been chalked off immediately. Palace are denied a killer second goal as Wickham pokes home Bolasie's cross but the linesman rightly waves his flag.
Tottenham running out of time to grab an equaliser and force an unwanted replay at White Hart Lane. Hennessey keeps out Onomah's volley as Palace survive. it has hardly been a backs to the wall job though.
Crystal Palace far surer of themselves now having seen off that brief spell of pressure from Tottenham. A flurry of free-kicks have even given them the chance to add to their lead but Yohan Cabaye has not had the required quality to test the Tottenham defence.
Caballero is hardly urging much confidence at the back and a horrendous beat away from a Hazard cross is another example of his poor start.
Fabregas forces Caballero into a good low save. Chelsea in control but City's kids not disgracing themselves.
We saw a sign of Dele Alli's mean streak in mid-week and there is another flashpoint as he bumps Yohan Cabaye off the ball when the ball is dead the Frenchman takes a nasty fall on the area around the pitch.
Inexplicable miss from Josh Onomah. Dele Alli's cross misses Eriksen and Onomah can't finish at the back post. Spurs turning the screw in this second half.
It's all Harry Kane again and it takes a last ditch block from Yohan Cabaye to turn his shot over the bar.
Chance for Tottenham. Harry Kane takes aim with his left foot but it goes just past the left post of Hennessey.
Back under way at Tottenham where the hosts have made one change with Christian Eriksen coming for Mousa Dembele.
Half time: Tottenham 0-1 Crystal Palace
An entertaining half ended in the grand manner with a fabulous goal for Crystal Palace which puts them in front at the break at White Hart Lane. Martin Kelly scores his first goal for five years to put the visitors ahead but Tottenham have had plenty of chances with Dele Alli hitting both posts but so far they are being outdone by Alan Pardew's men.
Goal: Tottenham 0-1 Crystal Palace (Martin Kelly)
Palace take the lead in the second minute of added on time. Wilfried Zaha feeds Martin Kelly who storms into the penalty area and lashes past Vorm at the near post. Fine finish and a great time to score for the visitors.
Harry Kane over a free-kick as we approach half time and Wayne Hennessey makes a good low save to keep out the shot. An all action first half thus far.
Palace have not come along to make up the numbers and they are a real threat in the final third. Wickham skips away from two challenges and feeds Adebayor, but his shot is blocked.
Game has settled down a little but it hasn't taken long for Emmanuel Adebayor to make an impression and he wants a penalty as he is taken out by Michel Vorm, but the Spurs stopper got a strong hand on the ball and Palace have a corner.
How are Tottenham not ahead? Dele Alli hits both posts from the same shot and Delaney is forced to lash the ball clear from underneath his own crossbar. Incredible moment as Palace survive.
Palsce so close to taking the lead. Kyle Walker heads the ball back to Michel Vorm but gets too much on it and the Dutch stopper is forced to get back and claw the ball away. Decent start to this game.
It is all action at the Lane in the opening minutes and might Crystal Palace have had a penalty? A cross from the right finds Mutch at the back post and his ball back in catches Bentaleb on the arm and goes behind for a corner. The Algerian certainly had his hand raised.
Spurs should really be ahead inside three minutes. A corner from the right catches Palace unawares and Alli ghosts in at the back post and it takes Yohan Cabaye's block on the line to prevent the hosts taking the lead.
Under way at White Hart Lane. Palace fans have sold out their allocation and are in good voice early on.
Teams are out at White Hart Lane we're almost ready to go in north London. Saturday was a little sterile for my liking and though Reading upset West Brom, there is plenty of room for more cup drama. here is hoping to starts now.
West Ham go into half time at Ewood leading 2-1 over Blackburn Rovers. Victor Moses and Dimitri Payet responded to Ben Marshall's opener. Meanwhile at White Hart Lane, both teams are in the tunnel.....
