Theo Walcott and Alex Oxlade-Chamberlain will miss at least the next three Arsenal games through injury, including the Champions League clash with Bayern Munich and the north London derby against Tottenham.
Both players sustained injuries in the 3-0 Capital One Cup defeat at Sheffield Wednesday on Tuesday, with Oxlade-Chamberlain taken off after five minutes with a hamstring problem.
Walcott replaced his fellow England international but was also substituted less than 15 minutes after coming on because of a calf injury and Arsene Wenger has confirmed.
They have subsequently been ruled out of the trip to Swansea on Saturday, the Champions League Group F return fixture in Munich on November 4, and the clash with Spurs at the Emirates on November 8.
Walcott and Oxlade Chamberlain will also miss England’s friendlies against Spain and France later next month but the Arsenal boss hopes they can return for the game against West Brom after the international break.
Wenger said: “Nothing has changed since after the game. They are out but the scans are today – it’s 48 hours afterwards.
“We hope they are light injuries, but they are out until after the international break.”
Walcott has been instrumental in Arsenal’s excellent recent form, scoring twice in six Premier League starts, while Oxlade-Chamberlain has impressed in seven appearances off the bench.
