Arsenal will be without club record signing Mesut Ozil for "a minimum of three and a maximum of six weeks" with a hamstring injury. The German international - a £42million buy from Real Madrid last summer - suffered the problem during Tuesday's 1-1 last-16 draw at Bayern Munich which saw the club exit the Champions League.
Wenger confirmed Ozil would definitely be out of Sunday's north London derby with Tottenham, but was not able to put a specific time frame on recovery. Midfielder Aaron Ramsey's return from a thigh injury has been delayed, and England international Jack Wilshere is sidelined with a broken foot. Sweden international Kim Kallstrom could be in contention for his debut after signing on loan from Spartak Moscow with a back injury while full-back Nacho Monreal is also available again.
Arsenal striker Nicklas Bendtner wasn't included in the travelling squad for the Bayern Munich tie because of a minor knee injury. The Denmark international was allegedly involved in an drunken incident in Copenhagen, for which Wenger confirmed he would face sanctions from the club following the unauthorised trip home. The 26-year-old is reported to have threatened a taxi driver, then unbuttoned his trousers and rubbed against the car, during an incident in the Danish capital while his team-mates were playing against Munich.
Wenger said: "Honestly I don't know really what happened because I haven't spoken to him. The only thing that is for sure is he had nothing to do in Copenhagen. Nobody gave him any permission to go to Copenhagen and he will be fined for that. "For the rest, he has created some trouble there I don't know, I will speak to him today." Bendtner has not played for the Gunners since February 2, but did start for Denmark in the Wembley friendly against England last week.
Asked whether this was the 'final straw' for the player, Wenger said: "He is at the end of his contract at the end of the season."
