Arsenal manager Arsene Wenger has named an unchanged side for this evening's trip to Southampton.

Theo Walcott continues in attack against his former club after scoring a memorable treble in the 7-3 win over Newcastle United on Saturday.

Alex Oxlade-Chamberlain also starts on his return to St Mary's, while Laurent Koscielny keeps his place in central defence ahead of Per Mertesacker.

Southampton boss Nigel Adkins makes three changes from the six-goal thriller at Stoke City, including a change of goalkeeper.

Kelvin Davis is dropped in favour of Artur Boruc, while Gaston Ramirez and Steven Davis replace Jay Rodriguez and Jos Hooiveld.

Arsenal: Szczesny, Sagna, Vermaelen, Koscielny, Gibbs, Arteta, Wilshere, Chamberlain, Cazorla, Podolski, Walcott

Saints: Boruc, Cork, Fonte, Yoshida, Shaw, Puncheon, Schneiderlin, S. Davis, Guly, Ramírez, Lambert
