Manchester United legend David Beckham sought out Manchester City striker Mario Balotelli for his autograph on Sunday.

Beckham's son Brooklyn, 12, collects replica kits and asked his dad to have a word with striker Mario, despite David being a legend with rivals United.

The Italian star, 21, duly obliged, handing over the shirt to Becks as his side lost 3-2 at home to United in the FA Cup on Sunday.

A source told The Sun: "Brooklyn has an impressive collection of kits from some of the world's top players. He's a big fan of Balotelli and really wanted a signed shirt.

"Despite City being United's rivals, Becks didn't mind as he's also a big admirer of Balotelli."

The ex-England captain, 36, watched the match with Brooklyn, younger son Romeo, nine, and dad Ted.
