Arsenal head to Napoli for a crucial match on Wednesday which could shape their season.
Arsenal are favourites to progress to the Champions League knockout stages with on game to go - but a collapse against Napoli could send their season into a tailspin.
A loss by three goals or more, combined with a Borussia Dortmund win at Marseille would send the Gunners crashing into the Europa League.
Team selection will be crucial, and here is how we predict Arsene Wenger will set his team out:
Jenkinson Koscielny Mertesacker Gibbs
Rosicky Ozil Cazorla
Arsene Wenger is likely to be forced into leaving out first choice right-back Bacary Sagna, with Carl Jenkinson set to remain in.
Then the Frenchman has two key decisions to make:
The defensive midfielder pairing will be crucial - Wenger will not want to change his formation, and so only two of Mathieu Flamini, Aaron Ramsey and Mikel Arteta will be selected.
Arteta was the only one to play 90 minutes on Saturday, and has been in impressive form of late - but we can see him sitting this one out.
Flamini's recent experience in Italian football with AC Milan should make him perfectly suited to this game, where breaking up Napoli's attacks will be paramount to their success.
Aaron Ramsey's superb season makes him undroppable in this key game - and so we expect Spaniard Arteta to be the odd man out.
The second decision is even tougher - a four into two choice for Wenger - which of Wilshere, Cazorla, Rosicky and Walcott should miss out?
We expect Walcott to play a part as an impact substitute, due to his pace, but also because a partnership with Theo Walcott could leave Carl Jenkinson exposed down the right.
Tomas Rosicky will be far better suited to this role, and with Jack Wilshere starting against Everton - we expect Wenger will give him a rest. Santi Cazorla should take the spot on the left side of Mesut Ozil in the centre.
Get this one right, and with Lukas Podolski nearing a return to full fitness - by time the Gunners play in the knockout stages, Wenger's choices could be even tougher.
