How do we know James hasn't been a tit during discussions with Benitez over his future?
People making assumptions and jumping all over the manager same as many did as I mentioned yesterday over Moyes/Drenthe/VDM before months/years later the dirty linen came out the laundry basket.
Until we know the facts of the situation you have to assume the player and manager dont see eye to eye therefore its the managers call to have said player training alone which in the animal kingdom is a show of dominance and makes the rest of the pack fall in line.
