Four players missing for Arsenal against West Bromwich Albion

Arsenal manager Arsene Wenger has revealed that four of his first-team squad will not feature against West Bromwich Albion on Saturday.

Lukas Podolski, Theo Walcott, Bacary Sagna and Laurent Koscielny all sat out of Tuesday's 2-1 defeat to Olympiacos, and will also take a place in the stands on Saturday.

Walcott and Podolski - both struggling with calf injuries - did start last weekend's defeat to Swansea City.

Meanwhile, French duo Sagna (foot) and Koscielny (thigh) have also failed in their bid to prove their fitness.
