Sir Bobby was a proper gentleman.
I remember watching an interview with him years ago. The topic got on to Maradona and his hand of god goal.
He wasn't bitter and twisted about that goal. Infact he said that Maradona missed a perfect opportunity to go down as one of the greatest sportsmen in history. All he had to do was to go up to the ref and admit that he handballed it, but he never and the rest is history.
