Arsenal vs Chelsea live: Score and updates from Carabao Cup semi-final

So, what can those subs inspire for the Blues? They need to make something happen sooner rather than later.

Palmer has started in a deeper position around the centre, with Arsenal sitting back for the moment as the hosts concede a corner.

Chelsea make the first changes of the night, with Cole Palmer and Estevao coming on for Delap and Hato.

Madueke gets free on the right again but this time he sees his cross sail into the gloves of Sanchez. This game is definitely heating up though!

There is a brief break in play however, with Gusto down and needing treatment.

Delap does well at the other end to win a free-kick around 30 yards out, towards the wing.

Fernandez swings it in but Rice heads away before Eze charges down Hato and Madueke wins a free-kick by the touchline.

Delap is booked for the challenge on the Arsenal winger.

Chelsea lucky to avoid giving away a free-kick in a dangerous area as Gusto and Delap have hands all over Martinelli and Hincapie before Pedro is fouled.

Arteta gets a yellow for his protestations.

Madueke gets away from Cucurella and clips a cross to the back post but there’s too much on it for Rice to connect.

An early check for a penalty here as Saliba is grappling with Pedro in the box before some pinball and then a shot flying wide.

‘Mutual holding’ is the call from VAR.

We’re back underway at the Emirates! A huge second half ahead as these two sides battle for a place in the League Cup final.

Cole Palmer and Estevao warming up on the Emirates pitch as we approach the second half.

A big second half up next as the players emerge from the tunnel in the capital.

“They haven’t laid a glove on Arsenal. They need to win the game – Arsenal don’t need to do anything” points out Paul Merson on Sky.

“It’s a dangerous game,” he adds as he ponders Chelsea’s tactics.

They’ve nullified the Gunners but they haven’t provided enough in attack to upset the hosts at all so far. That’ll need to change in the second 45 minutes.

Nevertheless, the Blues are still in this tie and they have plenty of options off the bench, not least Cole Palmer and the returning Estevao.

Arsenal are on their way to Wembley as it stands but there’s plenty of time left in this one!
