As a Man U fan - you have a very short memory - think Rio, Rooney, Giggs and of course Cantana. Have you also forgotten the "problems" between Arsenal/Man U in the pass - which broke out into brawls?? At least Suarez did not hit anyone.
"He who is without sin", blah, blah, blah.
Also where in the rules does it say one player HAS TO shake hands with another player - Did not Wayne Bridge refuse to shake Terrys hand - did you get all pissy about that??
Suarez is a douch - but then so are many of the Man U players. As for Sir Alex - perhaps the biggest douch of them all.
