The 1968 European Cup-winning player is the star of the "Paddy Crerand Show" on Manchester United's in-house TV channel, and discusses the weekend's talking points on a Monday night.
And when the topic turned to Sunday's Merseyside derby between Liverpool and Everton, Crerand couldn't disguise his disgust at the behaviour of Liverpool striker Luis Suarez.
Footage on 101greatgoals.com shows Crerand discussing Suarez's dive celebration in front of Toffees boss David Moyes, to which the former-United star said: "you wouldn't get fed up of punching him, would you?"
The United legend later insisted that "he shouldn't have said that" and assured his co-presenter Stewart Gardener that he was "just joking."
And Crerand later took to Twitter to continue his apology. On his Twitter account, Crerand said: "Ref Luiz Suarez what I said jokingly because opposing supporters will always have strong opinions on him. But a tremendous player for LFC."
Suarez was man of the match as Liverpool played out a 2-2 draw at Goodison Park. And the Uruguayan forward scored one, and forced an own goal, as the Reds raced into an early lead, before Everton pegged them back to earn a share of the spoils.
But it was Suarez's celebration after putting Liverpool ahead that Crerand took exception too, branding the Uruguayan's behaviour "disgusting".
After forcing Leighton Baines into conceding an own goal, the Liverpool striker sprinted back towards the dugouts and dived in front of Moyes, in reaction to the Everton boss's criticism of Suarez prior to the match.
Moyes had pinpointed Suarez as a diver.
Manchester United also played on Sunday, beating Chelsea 3-2 at Stamford Bridge to move to within one point of the Blues at the top of the Premier League table.
