The left back needs another operation on the metatarsal he fractured against Standard Liege on November 24. As a result he will sit out the remainder of the campaign.
“That is sad news because I rate him highly,” Wenger told Arsenal TV Online. “I had hoped that the first surgery would be successful.
“It wasn’t. The damage done on the bone was too much.
"He now needs a little bone transplant and that takes him out for the season.”
