Wenger left with just Giroud available as option upfront.
Arsenal have suffered yet another injury blow after front man Yaya Sanogo suffered a back problem while away on international duty with the France Under-21s, according to reports in the Daily Mirror.
The 20-year-old picked up the problem playing in an international against the Kazakhstan U21s last week and was immediately sent back to north London to have the injury looked at.
And this latest setback to Sanogo could not have come at a worse time for Gunners head coach Arsene Wenger, with the Frenchman currently badly short of numbers in attack at the Emirates following a raft of injuries in that position.
At present, France international Olivier Giroud is Wenger’s only fit and available centre-forward going into this weekend’s round of Premier League matches, with German forward Lukas Podolski having pulled a hamstring in the club’s UEFA Champions League playoff against Fenerbahce last month that has ruled him out of action until November.
And with want-away striker Nicklas Bendtner also not currently available for selection after the Denmark international spent all of the summer trying to engineer a move away from the capital, the last thing Wenger needed was to see yet another attacker go down injured.
