AC Milan coach Massimiliano Allegri insists he doesn't want to sign Manchester United legend David Beckham.

Beckham has been linked with a third spell at Milan.

"Beckham? I know Beckham, he is a great guy and a player of real class. However, you can't wipe out his birth certificate and Milan have chosen to focus on youth hopefully with support from an important champion like Kaka," said Allegri.
