Arsene Wenger has fired back at the Arsenal boo-boys.

Wenger was jeered and was the target for chants of: "You don't know what you're doing" after substituting fans' favourite Alex Oxlade-Chamberlain for public enemy number one Andrey Arshavin during last Sunday's defeat to Manchester United.

And the Gunners' manager could not resist a dig at his terrace critics, or defending Arshavin, ahead of an FA Cup tie against Aston Villa that could make or break his season. (Andrey Arshavin, Arsenal, Arsene Wenger, Aston Villa, FA Cup, Manchester United)
