The operating structure and culture at that club is rotten. It’s the same at Chelsea, there’s no togetherness, just infighting and, in Man U’s case, a host of overpaid players lacking discipline or any sort of commitment.
At least that’s the shite the media circus seems to report on. Oh, and their owners are complete arseholes, which trickles down through the club and into the fanbase, bar @Froggy, who’s sound.
