"Wilfried Zaha has done very little but late in the first half he's added the icing on the cake for Palace."
I have already called Graziano Pelle a giraffe, now I'll go rhino as he smashes into the back of his own player. Steven Davis beat him to a header and it took a good tip over from Tom Heaton to prevent a second. Pelle wanted that ball and instead left Davis in a pile on the floor.
Some added time here as a result of Fraser Forster's injury.
Wilfried Zaha uses his pace to power through and finishes with precision as Crystal Palace turn this game on its head.
Danny Rose produces a fine last-ditch tackle to deny Jamie Vardy pulling the trigger. Tottenham will welcome the arrival of half-time.

BBC Match of the Day commentator at Villa Park
"Aston Villa will be happier than Swansea that it is goalless. Villa goalkeeper Brad Guzan denied Bafetimbi Gomis on a couple of occasions and Guzan and his manager will be relieved that their clean sheet remains intact.
"But Villa have not been able to hold on to the ball for long periods in the first half."
Newcastle are pushing as half-time approaches. Ayoze Perez is trying to make things happen but the Arsenal defence is holding well, Nacho Monreal getting in the way of Perez's header. Two minutes of added time.
Brad Guzan is having a minor meltdown. No sooner has he waved at a cross to allow Wayne Routledge a great chance does he botch a bouncing clearance to whack it straight at Bafetimbi Gomis's leg. The ball loops into the air but Gomis gets too aggressive in pursuing it and it's a free-kick. A let off for Guzan.
Graziano Pelle is finishing like a giraffe trying to play football on roller skates. A header back across goal gets knocked down and lands at his feet, six yards out. Break the net... no. He nearly breaks the cross bar. What a waste.
What is this at the other end? Danny Ings whips an effort and again Kelvin Davis denies the visitors. He dived to his right and got a good hand on the strike.
...no messing from Glenn Murray, power and accuracy as he slams the penalty into the roof of the net.
OFF THE LINE. Chances begin to arrive at Villa Park and it is the man I just called 'twinkle toes' - Wayne Routledge - who sees an effort swiped away.
Brad Guzan is spared some blushes as he flaps at Gylfi Sigurdsson's free-kick delivery and Routledge turns the ball in, only for Ciaran Clark to smash it off the line. A certain goal denied.
Yannick Bolasie is fouled inside the area and penalty to Palace...
Game back on! David Nugent races away down the right and sends in a fine cross to the feet of Jamie Vardy, who hits a first-time drive into the back of the net.
Right place right time and this time Graziano Pelle's poor touch in front of goal pays off. He performs an air shot as Nathaniel Clyne's drive whistles across goal but Shane Long is thrilled, the ball lands at his feet and wallop, roof of the net from 10 yards.
In the Championship, defender Matt Kilgallon has nudged Brighton ahead at Blackburn, while Sheffield United, Peterborough and Rochdale have all enhanced their League One play-off hopes by taking the lead in their respective matches.
And at the bottom of that division, Crawley have edged ahead in their relegation battle with Leyton Orient.
League Two leaders Burton have scored twice inside four minutes against Tranmere as they endeavour to at least maintain their five-point advantage over Shrewsbury at the summit. And Cheltenham's woes at the foot of the division have deepened, with Exeter taking the lead at Whaddon Road.
Wilfried Zaha personifies Palace's frustrations with an altercation with Geoff Cameron, for which the winger receives a yellow card. The visitors are lacking ideas in attack.
Aston Villa attack, down the left side with Scott Sinclair, he slips in DELPH... good save.
Fabian Delph is without a Premier League goal this term but his strike is crisp and well dealt with at the near post.

"The way Newcastle are playing at the moment they are just waiting to be well beaten. They might need to change something to get themselves back into this game."
Newcastle are trying to get back into this after that Olivier Giroud double and they have a shout for a penalty as Ayoze Perez looks to be pushed by Gabriel, nothing given.
