Many people still see Sir Alex Ferguson and David Beckham's fallout as one of the biggest manager-player bust-ups ever, despite the incident occurring 16 years ago. A former Manchester United star has now recalled their infamous dressing room fight.
In 2003, after an FA Cup clash against Arsenal, Beckham and Ferguson were embroiled in a massive dressing room scuffle, setting off a process that eventually led to the player's move to Real Madrid later that year.
Former United and Uruguay forward Diego Forlan, who officially retired from the game earlier this month, has now recalled the infamous incident.
"It was a tremendous rift," he told the Daily Mirror.
"It was after a match against Arsenal in the FA Cup and Ferguson was not happy because Robert Pires had made a break down the left, Gary Neville was caught too far forward, and Beckham did not cover.
"In the locker room, Ferguson and Beckham began to insult each other. Every insult was worse than the last one and both men wanted to have the final word.
"Then Ferguson left, and it seemed that the discussion was over, but then Beckham said something else.
"Ferguson turned around and saw a boot lying on the floor and kicked it toward Beckham. A stud hit him in the eyebrow, and he was cut.
"We all saw the blood and thought 'no, that didn't happen', but within a moment both men were getting ready to fight.
"That was when Roy Keane and Van Nistelrooy stepped in to separate them."
