Arsenal manager Arsene Wenger has admitted that Mesut Ozil has no chance of featuring against Tottenham Hotspur in this Sunday's North London derby, telling The Telegraph that the German international will be sidelined for at least a few weeks.
Ozil limped out of last night's Champions League tie with Bayern Munich due to a hamstring strain, substituted at half-time for Tomas Rosicky as the Gunners crashed out of the Champions League despite earning a 1-1 draw at the Allianz Arena.
Wenger is already without key midfielders including Aaron Ramsey and Jack Wilshere, plus Theo Walcott on the long-term injury list, but was forced to concede last night that the early diagnosis of Ozil's injury is bleak.
He told The Telegraph: "He has a hamstring problem that looks quite serious. For sure, he is out against Tottenham.
"We have to make a scan to see how bad it is but he is out at least for a few weeks."
The 25-year-old will have a scan later today that should make a timetable for recovery more clear, but the playmaker's spell on the sidelines could not be more poorly timed.
Arsenal will have to reshuffle their pack once again ahead of a daunting run of fixtures, which begins at White Hart Lane this weekend.
Sunday's clash with Spurs is followed by Premier League clashes with Chelsea, Swansea City and Manchester City, all before an FA Cup semi-final against Wigan at Wembley next month.
Ozil could plausibly be absent for all of those crunch games at the business end of the campaign, which makes Ramsey's impending return all the more important.
Ramsey and Kim Kallstrom are both expected to resume full training this week, but will most likely fall short of contention for a starting spot against Spurs.
