Exactly, look at likes of respected greats of the game Patrick Vera, Roy Keane, didn't hear Arsenal or Man utd fans complaining about there assist or goal ratio,He does win tackles, his job is not to hit defence splitting passes its to help the team from the back. He has been one of our more consistent players this season. And no he will not score many goals or assists as its not what he is there for.
He is a defensive midfielder they never stand out they just get on with there job. Thought you would know that.
