A second half that was meandering nowhere has come to life now!

This has been coming since about the fifth minute. Gareth Barry nibbles at the heels of Diego Costa, Costa reacts and squares up to Barry. Once, twice, three times a head-charge [not a head-butt] and he thinks about biting him you know! He bares his teeth but changes his mind.

The two then hug. Referee Michael Oliver books them both. So two yellows make a red - Diego Costa sent off for the first time in a Chelsea shirt.

"Lukaku was like a man-mountain, unbelievable strength and to have the finish he does, incredible.

"Power, strength, pace. It is all of the qualities he has in one.

"You see what it means to Martinez as well, he paid the money, what would Chelsea do to have him now?"

Everton have the lead - and they have it in magnificent fashion as Romelu Lukaku rampaged past four Chelsea defenders to score.

Now - in this week when so many questions have been asked about Everton's fragility under pressure - can they hold on to reach Wembley?

Superb goal, that is why Everton paid the thick end of £30m for Romelu Lukaku. GAMECHANGER.

And he's only 22...

I'm not so sure that Kenedy will end as a left-back, but I can see him having a long career at the top level. He was very impressive against PSG and he's been one of the better players this evening. He plays a neat one-two and then takes the ball deep into enemy territory before the move breaks down.

"Willian looked strangely unhappy tonight, not really at his best."

Thibaut Courtois scoots off his line at double speed to sweep up from in front of Romelu Lukaku as Everton played it through the lines for once.

Chelsea take off their player of the season Willian as Oscar comes on. 

The closest we have come to a goal - you can't get much closer...

No efforts on target in the second half so far. There were none at all in the second half at Carrow Road. Was it something I said?

Twenty-five minutes to go. Nobody wants a replay do they? Let's settle this once and for all, right here, right now.

Chelsea are establishing a measure of control here and there is anxiety among the Everton supporters.

Everton were really pressurising Chelsea in the first half but have gone off the boil a little.

"That looked deliberate for me, there was a double movement and studs on Barry's knee. I'm not sure why Fabregas is shaking his head."

You can't keep Diego Costa out of the game as he pops up at the back post to attack Willian's cross, but Seamus Coleman clears superbly and then sees Costa nut him right in the back of the nut. 

Coleman is OK, and Cesc Fabregas is then booked for studding Gareth Barry on the knee.

"That is a real let-off for Everton. Costa just hasn't got the angle to finish it and it goes agonisingly across the goal."

Chance of the game! Diego Costa is played through by a beauty from Cesc Fabregas, Joel Robles comes out to close him down but gets his angle wrong, Costa is able to go around him and then shoot, left-footed - the ball squirms right across the line and away.So, co close!
