The Gunners suffered a 3-0 defeat to Sheffield Wednesday on Tuesday in the Capital one cup.
Arsene Wenger left most of the senior players out of the starting line-up but was forced to bring on Theo Walcott in as a substitute but the England international didn’t last long due to a calf problem he had nineteen minute into the game
Speaking after the game, Wenger confirmed that both players will face a scan today, with the results expected in the next 48 hours:
“he injuries are two muscular injuries and the injury damage I do not know. You have to wait 48 hours for the scans to see how big the damage is. Walcott is a calf and Oxlade-Chamberlain is a hamstring.
“I have to manage the workload of the players and at the end of the day I still think I brought too many experienced players here. We lost two players. Once I lost two players, I had Gabriel and Monreal and I did not bring them on as we could not afford to lose any more players.”
