DM) Mathieu Flamini
Considered the weak link in the team by many Arsenal fans, but realistically the only option in defensive midfield at the moment with Mikel Arteta out injured. He will have to be fully focused to negate the influence of Cesc Fabregas.
MC) Jack Wilshere
Started midweek on the bench due to an ankle injury, but if fully fit he is likely to come back into the side. Wilshere will have to be intelligent about his runs, against an accomplished counter-attacking team such as Chelsea he needs to time when to get forward and when to hang back.
AMC) Mesut Ozil
Ozil has to keep his place as the No.10 against Chelsea, he looks like a completely different player when deployed in the centre rather than out wide. Quietly provided two assists midweek, on top of a goal and an assist against Villa the previous week.
