Dutch fitness coach Raymond Verheijen speaking on Talksport radio station has criticised the way English and foreign clubs carry out their pre season training.
He insists that almost all teams compress fitness training before friendlies begin in the opening 2 week period. This puts too much pressure on player's bodies resulting in muscle and related injuries.
He recommends that this type of training be spread over the 6 week preseason period so as to relieve the burden on the players.
Mourinio's sides, he said, suffer much less injuries than others becaucse Mourinho aspises this philosophy and incorporates it in the preseason schedule.
In contrast to Arsenal who do not and as a result have suffered the worst rate of injuries in Europe!
