Chelsea full-back Jose Bosingwa will miss the rest of the season and the World Cup with Portugal as he requires further surgery on a knee injury, the Premier League club have confirmed.

Bosingwa had been back in light training after knee surgery but has now been ruled out for the season because another operation is required.

That means he is unavailable for Chelsea's challenge for a treble of Premier League, FA Cup and Champions League.

It also means he will not be able to play for Portugal in the World Cup Finals in South Africa.
