I'm no fan of Arsenal Whinger, but I reckon he's spot on with what he says.

A club team represents itself in any competition and no one else, and that's just the way it is (and rightly so).
I know that when Utd are in Europe, I couldn't give a **** about them representing England or the UK, and it's not as if the whole English nation is gonna get behind Arsenal to win the CL is it?
