Connor Ronan comes close but cannot get the winner for Wolves.

No-one has found the winner yet. Into the last minute. Can a Wolves players make themselves a hero?

Into the last five minutes.

Inches from the winner.

Yaya Toure strides forward and has a low shot pushed away by Will Norris but Leroy Sane cannot get the follow-up on target, shooting agonisingly wide from eight yards out.

The only game remaining. Are we heading all the way to penalties?

Young substitute Edward Nketiah comes on to turn the game around for Arsenal.

I can't understand how this game is still 0-0. There have been lots of chances, plenty of them falling to Wolves.

The possession and territory through has been all Manchester City's.

As it stands though we are heading towards penalties.

Final 15 minutes of extra-time under way at Etihad Stadium.

Come on lads, we need to get to bed.

Kyle Walker on for Danilo - Manchester City's fourth substitute of the game.

That is allowed in the League Cup.

Bet you forgot about that rule change.

Norwich are not happy.

James Husband is hauled down in the box by Mathieu Debuchy, but the referee signals just a goal kick.

Debuchy flungs his arm across Husband's face, but no decision given to the Canaries.

Boss Daniel Farke on the bench cannot believe it.

Arsenal looking to wrap this game up and Edward Nketiah - on a hat-trick - shows blistering pace to run clear, but his shot from the angle is kept out by Angus Gunn.

City nearly break the deadlock on 100 minutes, but both Sergio Aguero and Raheem Sterling have goalbound efforts blocked by Wolves defenders.

Another Arsenal youngster Josh Dasilva looking to get into the action, but he flashes his cross across the box and it evades everyone.

Into the final 15 minutes of extra-time at Emirates Stadium.

Manchester United

Manchester United manager Jose Mourinho speaking to Sky Sports: "We were in the game from the first minutes, pressing and forcing things, the attitude was good.

"Scott McTominay did very well, strong in the midfield. Axel Tuanzebe started maybe a little shaky, but then we got stability and he came into it.

"There were no injuries either, so it is a good day.

"I believe that Phil Jones will be fit for Saturday against Tottenham, but apart from that I have no news.

On his 400th match in English football: "Of course I still get the same thrill from it, but 2004 was along time ago. I am more mature and have a different way to react to things."

30 minutes of additional play under way.

Great.

Manchester United

Manchester United goalscorer Jesse Lingard, speaking to Sky Sports: "I thought we were in control. We had to put things right today. We have learned from the weekend and we want to move on.

"It was my first header in a long time, but I am just happy however they go in.

"It is always good to win trophies, especially this one which comes so early in the season."

Norwich goalkeeper Angus Gunn has made a number of excellent stops today. This is another.

Francis Coquelin lofts a cross into the box, Olivier Giroud takes it on the volley, but Gunn pushes the ball away from danger.

Into extra time we go.

Claudio Bravo has been the hero for Manchester City today.

This finished a bit ago.

Did I mention it?
