Arsenal endured a torrid afternoon on Saturday as Francis Coquelin was forced off in the 2-1 defeat to West Bromwich Albion.
The French midfielder departed the action following a challenge with Claudio Yacob and now faces two months on the sidelines after suffering a knee ligament injury.
Coquelin has been ever present in the Gunners' side since breaking into the first-team in January and Wenger is now left with a selection headache in defensive midfield.

The manager has hinted Calum Chambers could deputise in Coquelin's absence but has also suggested he may have to take action in the January transfer window.
In his press conference ahead of Arsenal's crucial Champions League tie with Dynamo Zagreb, Wenger confirmed his stance.
“I’ll do what’s needed in January even though in January it is not an ideal transfer market,” he told the Mirror.
Now, that certainly doesn't suggest the Frenchman will be going gung ho in the search of a new midfielder, but at least he will be assessing his options.
The January transfer window is a notoriously tough time to get major deals done. Many clubs are looking after their own interests and are reluctant to part with their star players with a limited time available.
While the new year will offer Wenger the chance to bulk up his squad, their title hopes could be significantly dented by then with six Premier League fixtures still to play before January 1.
