Manchester United boss Sir Alex Ferguson clashed with a linesman during their FA Cup draw with Chelsea.
The Daily Mail says Fergie was minding his own business on the touchline in the FA Cup quarter-final against Chelsea when the linesman barged in to him.
But instead of exploding in fury, Ferguson saw the funny side and cracked a smile afterwards while rubbing his arm where he had been hit.
ITV pundit and former United player Roy Keane also found the whole thing amusing, making a joke in the studio referencing his outspoken views over the Nani red card.
