The most pressing issue Erik ten Hag had on his to-do list upon his appointment at Manchester United was to fix the rotten culture at the club.
The Red Devils had reached 'sleeping giant' stage, a titan of a club sleep-walking into the abyss without a trophy in five years. While he hasn't had the chance to end the silverware drought just yet, Ten Hag has already made great strides at sorting out the atmosphere in the United dressing room.
He appears to have gone about doing this in a way eerily similar to his big-six counterpart Arsenal boss Mikel Arteta. The Spaniard is famed for being quite the disciplinarian with his Gunners troops and is keen to make clear he will not tolerate any slackers or troublemakers.
