Arsenal reached this point of the competition after beating West Brom away from home in a penalty shoot out.
Arsene Wenger is using the occasion to rest several of his first team regulars ahead of crucial Premier League games as the Gunners look to maintain their lead at the top of the table.
Wenger will be determined to make up for the club’s exit to then League Two side Bradford City in this tournament last season.
Jose Mourinho has also made changes, with key first team players taking a rest from normal duties.
Chelsea will be looking to make up for the last time these two clubs met in this competition, when the Gunners ran out 5-3 winners in an entertaining match at Stamford Bridge.
This is a tournament Mourinho holds close to his heart because it was the first piece of silverware he won during his first spell in charge of the West London team.
