Maybe because nobody can answer that (including you) apart from ETH? Seems strange that you can't understand that. Fred was also shite so it's not like it's even relevant either.
You must he wearing rose tinted glasses then. If by tussles you mean fouling when he's already lost his man or tackling when he's given foolishly lost the ball after 5 or 6 touches, then sure.
As for "see atletico game". The game he turned up his collar for? What a load of nonsense. As if we haven't seen him jogging around in no man's land and giving away needless fouls for years. You've chosen a strange hill to die on defending a Championship player stealing a living at United, especially when the best you can come up with is "tussles and strong tackles."
