Arsenal injury, suspension list and return dates vs. Chelsea: Piero Hincapie, Riccardo Calafiori latest

Seeking a second knockout success in a matter of days, Arsenal hit the road to face Chelsea in Wednesday's tantalising EFL Cup semi-final first leg.

The Gunners have dispatched Port Vale, Brighton & Hove Albion and Crystal Palace to progress to the final four, and they are now just 180 minutes from a Wembley showdown with either Manchester City or Newcastle United.

Mikel Arteta's men head across the capital on the back of an emphatic FA Cup success too, coming from behind to see off Portsmouth 4-1 in the third round thanks to a Gabriel Martinelli hat-trick.

Here, Sports Mole rounds up all of Arsenal's latest injury and suspension news ahead of the clash with Chelsea, who battered Charlton Athletic 5-1 in Liam Rosenior's first game in charge over the weekend.
