actually he has been quite petulant to the ref and being subbed a number of times, one example is After being pulled back by the opponent he turned around and started shouting at the lineman. Which, regardless of what has happened, isn’t the correct course of action, I forget the opponent but it was a CL game.
He is neither a saint, as you make out, nor a sinner that others try to do, but he is a human prone to peaks and troughs in performance. But if pep/management has questions about his attitude/ability (a fair conclusion after him not starting or featuring a lot recently) then I don’t think it’s that much of a stretch to say that there are signs of it.
As I’ve said before, I would rather we have him and keep him than lose him.
