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.
