Chelsea could face a fight to hang onto defender Cesar Azpilicueta in January.

The right-back has failed to hold down a regular starting berth and has been tipped to leave Stamford Bridge.

But according to reports in Spain Bilbao are looking for more depth and an alternative to Androni Iraola.

Also the Basque side have funds after selling Javi Martinez to Bayern Munich.

It remains unclear as to whether Chelsea will allow him to leave despite his lack of playing time.
