Louis Saha admits fights like the one involving Leroy Sane and Sadio Mane are "hard to control" and they "happened" at Manchester United.
The Frenchman, who signed for the Red Devils in January 2004, stopped short of naming any individuals involved, but confessed dressing room clashes were not out of the ordinary. Bayern Munich recently had to deal with a dressing room bust up as two of their forwards clashed.
It left Sane with a bloody lip as Mane was fined by the German club. Bayern demand high standards, as do United, and the pursuit of excellence can lead to heightened emotions, which may often boil over. Roy Keane skippered the club for years and has made no secret of his demands over the years.
