Except he didnt. That season was the lowest number of apps hes had at that point of his career:

22 apps in PL and 36 apps in all comps that season, thats the lowest numbers compare to previous seasons and he had 3 games suspension thanks to his red card against spurs earlier. This myth about Ole running him to the ground needs to die especially now people giving excuse to Ten Hag in the same situation; "the medical team gave "OK" for player "X", "Y", "Z" to play not Ten Hag fault."
Funny for some reason that excuse didnt apply for Ole...
