Yes I was at the game.Did you watch the game?! Walker had an absolute weston. Not even close to a 6.
What you don't seem to be getting is this discussion of Carroll is not based on last night, but a collection of performances he's put in.
Having read many write ups on the game from a variety of sources you are the first person I have come across that thinks Walker had a mare (yes, he was guilty of a poor mistake), but you are entitled to your opinion.
Carroll has not been shit. Is he our best CM? no. But the way he is being spoken about is nonsense and massively exaggerated.
