Arsenal forward Danny Welbeck has failed to recover from a knee problem and has undergone surgery with a specialist.
The England international was back in training following a lengthy spell on the sideline and seemed close to a return to match action, but recent developments have led to surgery on his left knee being required.
The former Manchester United man has failed to recover naturally once his training was intensified and is set for a few more months out of action for the Gunners.

The 24-year-old has been out of the picture since April and his last game for Arsenal was the 0-0 at home to Chelsea last season.
Welbeck's return from injury would have given Arsene Wenger more options upfront, but now the French manager will have to persist with Olivier Giroud and Theo Walcott.
A statement on the club's official website read: "Danny Welbeck has undergone surgery on his left knee after being unable to sufficiently step up his rehabilitation work.
"The striker has been working throughout the summer to recover from the injury sustained at the end of April.
"It had been hoped he would avoid surgery but after increasing his training workload, the injury to his cartilage did not respond as well as hoped and the decision was taken last week for him to undergo surgery by a leading specialist in the field.
"Danny is now expected to be out for a period of months and everyone at Arsenal wishes him well."
It is a shame for Welbeck who will have been itching to get back after such a long period out, and with the season now in full swing he faces a battle to be fit for the incredibly important Christmas period.
Despite only scoring eight goals in 34 appearances during his debut season in North London, the former United man produced some top quality performances for the Gunners.
Often played out of position, following the return of Giroud, Welbeck's willingness to do the hard yards and never stop chasing the ball was a massive bonus for Arsenal.
With the small matter of a European Championships in the summer, Welbeck will be hoping for a swift return to stake his claim for a spot on the plane to France.
