Arsenal's 2-0 win over Borussia Dortmund has been dampened by injuries to Mikel Arteta and Yaya Sanogo, with both players expected to be out for some time.

The setback has taken Arsenal's injury count to ten which will be a major problem given the deluge of games coming up in the Christmas period. Arteta has seen a recurrence of his calf problem and Arsene Wenger believes that he will be out for a long period looking at the severity of the injury.

Sanogo, who missed a major part of this season, scored his first goal for the Gunners to give Arsenal the lead but had to be taken off before the final whistle as he felt his hamstring.

"Mikel Arteta doesn't look good. I think he will be out for a while. It looks quite serious. The injury situation is a problem because we have many games. The injuries are difficult to take on the chin," Wenger said after the game.

It was an opportunity for the Frenchman to build on this moment and show his true potential as a player with the media and pundits slagging him off for his profligacy in front of goal in an Arsenal shirt.

The Gunners are also without Jack Wilshere who is out with an ankle injury and will see a specialist on Thursday to assess if he will need surgery to restrict further damage in that region.

It is unfortunate for the 22-year-old, who was finally showing glimpses of his ability and had been praised by the media for his performance in a deep holding role for England.

Should he need surgery, he will be out for a minimum of three months, a huge blow for the Gunners, whose sole priority would be to progress into the further stages of the Champions League.

Meanwhile, the Gunners are also missing Danny Welbeck, who was out of the squad with a knee injury alongside Theo Walcott, who had a problem with his thigh in training before the game against Manchester United.

Mesut Ozil, Mathieu Debuchy and Serge Gnabry remain long term absentees as the Gunners look for a solution to their injury problems.

Arsenal will travel to West Bromwich Albion in the upcoming weekend in a bid to resurrect their league campaign, where they are currently languishing in eighth spot, two points behind fourth placed Manchester United.
