Supposedly, it's a temporary measure because of the impending World Cup (which I will not be watching), as some players could easily have been plying 70+ games given all these competitions..
Player union demanded action as so many of their players were monitored and are playing and have been played in the red zone; under Poch we were one of the PL's biggest culprits and that did continue after, Kane for example spent the last 3 season 50% of the time in the red zone.
Something had to change., it's destroyed some players careers through injury and loss of form..
