Someone mentioned it earlier, but there's a certain amusing irony in people using his apparent disloyalty and indiscipline as a reason why he doesn't belong in the same category as players they never saw, and evidently know little about. George Best, for example, was frequently disciplined and fined for turning up to training (and occasionally even games) hungover or drunk, or not turning up at all! He even threatened to retire - twice! - in an attempt to sack off his obligations to the club, and left under a cloud in the season we were relegated. Yet he's rightly remembered as a top tier legend for the good things he did for us on the pitch, rather than the years of not giving a shit. Even watching people try to casually handwave the likes of Ronaldo, Rio or Keane flirting with other clubs as all kinds of different gravy is kinda cringey.
If we applied the same shifting subjective criteria to all our supposed legends we'd likely be left with just Sir Bobby and Scholes.
