I really dont believe he does.
He may manage teams and as they are limited in ability encourage them to be physical, and let other teams know they are there. Thats football always has been and always will be.
If however he or any other manager encourages his players to purposely injure opponents then they are most certainly as you say. If you think for one moment that City managers past have not told their players to put their foot up an opponents arse you are either quite young or very forgetful.
