Norwich absolutely deserve it. The goal Chelsea conceded summed their performance up - no pressure on the ball, no pressure to stop the cross. They think the match is over. That's what Norwich deserve.

To extra time we go!

Wow! I mentioned that Jamal Lewis has had a good game - he's not stopped all game. It's a brilliant ball into the box, and the marking is not great, but it's all about the finish, what a finish that is - and what a feeling for the youngster.

Josh Murphy is flagged offside as Norwich search for an equaliser.

Murphy is then ushered away from a ball over the defence by Andreas Christensen as the visitors come forward again.

Not long left...

FOUR minutes of time added on.

That's a big chance for Alvaro Morata. It's a beautiful ball from Pedro, but it's like Morata doesn't believe he can get there, because he was so close to it, he shouldn't have missed that. Another big chance missed.

Pedro is playing left-wing back now. He can play anywhere on the pitch.

It's not been his best night but you want to have him in your squad.

Speaking of Pedro...

... he's just played a superb ball for Alvaro Morata eight yards in front of goal. It's surely a goal? It has to be a goal! Morata pokes out a foot, and misses his kick.

CFC Warrior: Am I the only one seeing that Pedro has done nothing today. Conte should surely see the need for a change. Musonda maybe?

I think Kenedy took his chance tonight. He's been up and down that left hand-side all game, and he created the goal for Michy Batshuayi. He's really done himself no harm, and he's showed Antonio Conte that he's an option on that left-wing.

More changes for both sides, Kenedy off, N'Golo Kante on for Chelsea while Todd Cantwell replaces Grant Hanley for Norwich.

Four minutes remaining.

Alvaro Morata has got genuine quality, he really has, but he's had a tough first season in English football so far. You just have to look at tonight as a missed opportunity for him as well, because it was a chance for him to get the goals going again, by scoring against a weaker side.

All eyes on Stamford Bridge then.

Ten minutes to go and both sides turn to their substitutes bench. Alvaro Morata is on for Michy Batshuayi and Andreas Christensen replaces Ethan Ampadu.

Wes Hoolhan replaces Harrison Reed for Norwich.

Burton Albion defender Stephen Warnock: "Wigan have been really solid and compact throughout the game, and they can be really proud of the clean sheet they're going to get, because Jamie Jones in goal hasn't even had anything to do."
