David Beckham last night warned Real Madrid he will quit if he is left to sit on the bench.

The former England captain is prepared to rip up the two-year contract extension he has been offered by the Spanish giants if manager Fabio Capello continues to leave him out of his team. Becks started as substitute for the sixth time this season against Barcelona today and hinted it is massively affecting his chances of signing a new deal. But the 31-year-old midfielder, who can negotiate a lucrative free transfer away from Spain in January, also said he has no intentions of retiring.

In fact, he only came on for the final 5 minutes against Barca, and this could be the end for him at Real.
