Per Mertesacker returns to the heart of defence for Arsenal's trip to Norwich City this afternoon (12.45pm).

The centre-back will start alongside Thomas Vermaelen at the back for Arsène Wenger's side, with Laurent Koscielny set to feature at right-back for the first time this season.

The team is otherwise as you were from the impressive victory over West Brom two weeks ago at Emirates Stadium.

Mikel Arteta and Aaron Ramsey continue in midfield, anchored in the middle by Alex Song.

Robin van Persie will be keen to continue his lethal scoring streak in the Premier League, flanked once more by Gervinho and Theo Walcott.

Team in full:
Szczesny, Koscielny, Vermaelen, Mertesacker, Andre Santos, Song, Ramsey, Arteta, Walcott, Gervinho, Van Persie.

Substitutes: Substitutes: Fabianski, Djourou, Rosicky, Coquelin, Benayoun, Arshavin, Chamakh.
