Arsenal will be without England forward Danny Welbeck for several months after he underwent surgery on a knee problem.
The 24-year-old, signed from Manchester United on deadline day in September 2014, last played for the Gunners in April, missing both the FA Cup final and end-of-season internationals.
Despite hopes Welbeck would be able to recover from bone bruising around the knee, Arsenal announced in a statement on Thursday the player had needed an operation and was now set for an extended spell of rehabilitation.

It will no doubt infuriate fans that the Gunners are now left to rely on Olivier Giroud and make-shift striker Theo Walcott.
Welbeck scored eight league goals last term - and also scored a stunning hat-trick in the Champions League against Galatasaray.
