24/01/2018 - Chelsea - Carabao Cup - First Team - H

WE'RE GOING TO WEMBLEY - AGAIN!

Ospina goes long with the goal-kick...

Alonso looks to win a corner by hitting the ball against Bellerin, but it then bounces back off the Chelsea man's legs, prompting him to fall over into a pitchside microphone

This is it... one last push Gunners - COYG!

There will be a minimum of four minutes of added time before the final whistle

Alonso has a free-kick... but he absolutely hammers his effort over the crossbar, posing no threat to David Ospina

Shkodran Mustafi hits a long free-kick from deep and Xhaka races after it before flicking a sliding effort just wide of Caballero's near post

Great block! Davide Zappacosta hangs up a cross for Alonso at the far post, but his volley is blocked by Hector Bellerin

We're inside the final 10 minutes now at Emirates Stadium

Crucial save!

The ball is put across by Ozil for Iwobi, who has clear sight at goal from the edge of the area, but his low strike is turned away by the legs of Caballero

Monreal goes into the book after he grapples with Hazard

Victor Moses goes into the book for a poor challenge on Iwobi

Alexandre Lacazette with some lovely link-up play... and his low cross deflects and Granit Xhaka is on hand to provide the finishing touch

Alex Iwobi looks to pull the ball back across goal, but Cesar Azpilicueta clears it behind for a corner

We're back underway for the second half at Emirates Stadium now

Here's what you're saying after that opening 45 minutes...

Confirmation there that Nacho's header has officially gone down as an Antonio Rudiger own goal

Close! Mesut Ozil gets the ball in the area but his right-foot shot deflects narrowly wide of the far post

We'll have a minimum of three minutes of added time before the half-time whistle

Alexandre Lacazette makes a run in behind but is flagged offside - that one looked close...

Jack Wilshere goes into the book as he puts in a misjudged tackle on Barkley

Willian's evening is going to end prematurely - Ross Barkley is getting set for action

Willian is struggling with an injury here...

Eden Hazard picks up a yellow card for stopping Mesut Ozil as he looked to break

Pretty sure that one's going to get taken away from Nacho - but we're definitely giving him that goal...

Monreal finds himself in the right place and his headed effort finds the net after ricocheting off of both Marcos Alonso and Antonio Rudiger

A bursting run from Jack Wilshere ends with Willy Caballero keeping out his close-range strike, before slapping the ball away from the onrushing Nacho Monreal

Pedro with a low, angled ball in behind... and Eden Hazard finishes past David Ospina

A reminder that VAR is also in operation tonight, for the fifth time in English football

Chelsea have the ball in the net... but linesman Scott Ledger has his flag up for offside

The goal will not stand

The winner goes to Wembley - here we go... COYG!

Mertesacker in tonight's matchday programme:

"Henrikh was a huge fans’ favourite at Dortmund because of the way he played. He linked with other players, always created chances for others, and that’s something we want. His record there, both scoring and assisting, was pretty amazing. At Manchester United, he didn’t have the same playing time but he made an impact as well. I’m just looking forward to training with him on a consistent basis and watching him grow towards making the contribution he made at Dortmund. He wants to prove that he’s coming back to his best and we’re here to help get the best out of him. I think he fits perfectly to this football club."
