Sir Alex Ferguson recalled how it was a sign of his confidence that when the Frenchman first arrived, he'd puff out his chest and turn up his collar and prepare to dominate his new arena.
As is the case with most footballers' style choices, it was largely down to superstition.
He once revealed it was no gimmick, merely that he played with his collar up during a cold day and, with his side winning that particular match, decided to keep it that way for good luck.
Although other theories abound, including that he made the decision before a Manchester derby in 1993 when feeling a bit of a twinge in his back, this has been the Frenchman's version of events.
