His son Raphael revealed his dad's torment to a United fan in Barcelona.
The Mirror reports the pair had watched the season's climax on TV and thought the Reds had held on to the title as rivals Manchester City were being held at home by QPR.
But City's Sergio Aguero scored a winner with just seconds left to hand the Premier League trophy to the Sky Blues on goal difference.
Raphael, 23, said his dad, famed for his Kung Fu attack on Crystal Palace fan Matthew Simmons in 1995, kicked out at the coffee table.
He told United supporter Jonathan Cruise: "It smashed to pieces. My dad was angry and upset. He still adores United and we thought they were going to hang on to the title."
