Arsenal are back in action tonight when they take on CSKA Moscow in the Europa League.

The clash takes place at the VEB Arena in Moscow while kick-off is scheduled for 20:05 (GMT).

Goalkeeper: With Petr Cech ruled out, David Ospina is almost certain to start.

Defence: Mustafi put on an impressive display during Arsenal’s win over Stoke and is set to start alongside Koscielny, Monreal and Bellerin as part of a back-four.

Midfield: Xhaka, Ramsey are expected to keep their place in Arsenal’s midfield with Ozil in his favoured number ten role. Meanwhile, Wenger has a decision to make whether to start both Wilshere and Mkhitaryan away from home against CSKA.

Striker: Alexandre Lacazette returned to first-team football over the weekend and got himself on the scoresheet. However, Wenger is unlikely to start the France international who only recently returned from a knee operation.
