What a move! A brilliant from Tavernier, great energy and fitness and a great pass at the end of it, a chance for Isaiah Jones to make himself a hero.

Superb, flowing team move from Boro and they come close to another shock.

Isaiah Jones is in to write his name into FA Cup folklore, striking a low drive which is pushed out by Hugo Lloris.

Harry Kane through on goal, but is thwarted by Joe Lumley.

The Spurs striker was off anyway, wouldn't have counted.

Crystal Palace

Crystal Palace matchwinner Jairo Riedewald to BBC Sport: "It was hard work. We knew what we would get, they made it very tough for us. We’re just happy we won the game. At half-time we said they had some space in between the lines so let’s use that. We scored first goal and they responded very quickly. It started to get scrappy. We’re just lucky we won the game.

"The keeper knocked it over a defender's head. I was about to go for the half-voley but changed my mind and got it onto my right foot.

"We’ll enjoy this win tonight. One game away from Wembley, it would be nice."

Spurs almost win it.

Son Heung-min swings in the corner to the near post, Eric Dier flicks the header just over.

Five minutes to go before extra-time.

Jonny Howson has covered every blade of grass tonight and slides in to intercept Son Heung-min's cross.

Manchester City

Manchester City boss Pep Guardiola, speaking to ITV, on Riyad Mahrez scoring more goals than in previous seasons: "He is playing in a position he has played in all his career. We know the quality he has. I am proud the most because he loves to play football.

"For him football is not a profession, it's a joy."

On Jack Grealish: "He had chances in the first half that were more difficult. He came back from injury and he is playing at a really good level."

On the prospect of a Premier League, Champions League and FA Cup Treble: "I am not going to buy this argument. [Manchester] United is the next game."

Brilliant run from Steven Bergwijn, nice skill, nice touch, but what a tackle from Paddy McNair just when they needed it. He just gave him the opportunity because he tried to take it on his right foot rather than his left.

Tottenham think they are in for the winner courtesy of sub Steven Bergwijn, but the Dutchman sees his shot from close range brilliantly blocked by Paddy McNair.

That was the chance, that was THE chance.

It falls for Folarin Balogun 15 yards out, seeing a pass flicked to him by Andraz Sporar. but the on-loan Arsenal man leans back and shoots over.

Jonny Howson has been the best player on the pitch.

Approaching the last 10 minutes, it's been a tight affair so far.

No extra time/penalties would be nice.

Tottenham have been flat and haven't looked as dangerous as they did in the first half.

A change for Boro as Duncan Watmore is replaced by Folarin Balogun, on loan from Arsenal.

How he would love to score his first Middlesbrough goal tonight.

Peterborough United boss Grant McCann, speaking to ITV: "I am really proud of our performance. Defensively we were well organised. And we had a massive chance to go 1-0 up. On another day we do, but when you play against a top-class team they keep probing and probing. I've said to the boys that this is the bench mark. There is a lot of quality in the dressing room."

A couple of times Harry Kane has got frustrated with the early ball not being put in.

It's all over. Crystal Palace are into the FA Cup quarter-finals after a very close game.
