Ferdinand is part of BT Sport’s punditry team for Liverpool’s lunchtime trip to Craven Cottage and before the game, he spent time taking pictures and signing autographs with supporters.
But the Manchester United legend politely refused to write his signature on the top of a fan who was in the Fulham section but was wearing Liverpool’s new shirt.
Ferdinand filmed the exchange and posted the video on social media. The fan can be heard asking the former England defender: “Can you sign that?” – to which he replied, “He just asked me to sign a Liverpool shirt, are you crazy?”
He then added: “I can’t sign it, I can’t sign a man in a Liverpool shirt.”
The fan’s friend had an item signed, but when Ferdinand was told he was a Liverpool fan, he joked, “Give me that back!”.
Ferdinand played 455 times for Liverpool’s rivals United after joining from Leeds in 2002 and won six Premier League titles.
However, he has previously gone on record to reveal an admiration for Liverpool when he was growing up.
“As a kid, Liverpool was the team that was doing well, with players like John Barnes and John Aldridge, and United weren’t winning anything,” he told MUTV in 2009.
“On my estate [in Peckham]all my friends were Liverpool fans.
“But I was more of a fan of the players than the clubs. Players like John Barnes, Paul Ince, Paul Gascoigne.
“But once United came for me, it was a no-brainer. I was afraid if I didn’t take the opportunity, I’d never get it again.”
