Arsenala's injury list has gotten bigger in recent days following injuries to Yaya Sanogo, Wojciech Szczesny, Mikel Arteta and Jack Wilshere, but it is not all bad news. According to Arsène Wenger, Mikel Arteta will miss 2-3 weeks with another calf strain, but Mathieu Debuchy is only 2 weeks away from first team training, and Laurent Koscielny is again in the squad. Wenger has not yet decided whether to bring Koscielny back into the starting lineup.
Yaya Sanogo scored his first goal for Arsenal on Wednesday, but came off with what looked to be a hamstring problem. It was, however, only cramp, and the striker was pictured in training on Friday. Danny Welbeck, who has had a knee complaint, was also involved in training on Friday, as was Theo Walcott, though the latter is thought not to be available for tomorrow's trip to the Hawthorns or Wednesday's match with high-flying Southampton.
Wojciech Szczesny may still be kept out on Saturday with a pelvis complaint, which would mean Emiliano Martinez would continue in goal. Elsewhere, Olivier Giroud is in line to start his first league game of the season.
