AMR: Alex Oxlade-Chamberlain
A player in fine form in pre-season so far, Alex Oxlade-Chamberlain should start on the right wing again on Sunday, especially with Sanchez still out after his participation in Copa America.
AML: Mesut Ozil
Out on the left, Mesut Ozil has impressed in pre-season and could be a key player for Arsenal against Chelsea at Wembley.
AMC: Aaron Ramsey
In place of players like Cazorla and Sanchez, Aaron Ramsey could get a chance to score another Wembley goal in this more advanced midfield role.
FC: Theo Walcott
Starting up front as he did in the FA Cup final, Theo Walcott seems likeliest to lead the Arsenal attack, and he has a fine record against Chelsea.
