Because he is a top class midfielder, the best Aston Villa player of his generation and, along with his present team mate Milner, they are probably the second and third best Villa players of the Premier League years.
He's not a top class midfielder, Essien, Xabi Alonso, De Rossi, Schweinsteiger, Barry?
No, he's just a good solid CM.
Of course, he doesn't have a foreign name, so he can't be any good
I think the general point is that Barry's best days are behind him, he's slow as ****, and he is surrounded by truly world class players... a group that he doesn't have a swipe card to get into.
