Theo Walcott has kept his place at the centre of a three-man attack for Arsenal's match against Newcastle United.

Gunners boss Arsene Wenger makes one enforced change to last week's win over Wigan Athletic, with Laurent Koscielny in the starting XI for the ill Per Mertesacker.

Newcastle welcome back Chieck Tiote for the trip to North London, while Gabriel Obertan is handed a rare start ahead of the injured Vurnon Anita.

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

Newcastle: Krul, Simpson, Perch, Coloccini, Santon, Bigirimana, Tiote, Cisse, Marveaux, Obertan, Ba
