Having narrowly edged out West Brom in Round 3 through penalties, Arsene Wenger’s side will be hoping to put one over on old foe Jose Mourinho, who he is facing for the first time since his return to English shores. The Chelsea manager’s first piece of silverware with the club was in this competition while Wenger is still chasing his first trophy since 2005.
Both sides will be expecting a high scoring affair considering their Round 4 clashes last year had a cumulative total of 21 goals, with Chelsea beating Man Utd 5-4 and Arsenal edging Reading 7-5.
Elsewhere this evening Man Utd will host Norwich and will be aiming to build on their 1-0 win over Liverpool in Round 3 of the Capital One Cup. There are some exciting match-ups outside of Manchester as well with Birmingham playing Stoke, West Ham travelling to Burnley and Leicester facing Fulham.
