thumbnail Hello,

The European champion is aiming to firm up its interest, with L'OM willing to listen to offers in excess of 10 million euros for the 22-year-old Spanish right back

Chelsea has made a "serious approach" for Olympique de Marseille right back Cesar Azpilicueta, according to the president of the French club.

The Spaniard would be Roberto Di Matteo's fourth summer signing, as the Italian looks to add depth and quality to his Champions League-winning side.

Azpilicueta appears to be the next name on the list, with Marseille reportedly willing to listen to offers of over 8 million pounds.

Marseille president Vincent Labrune, is quoted in The Sun as saying: "Chelsea have made a serious approach for Cesar [Azpilicueta]."

Chelsea is short on options in the position after allowing Jose Bosingwa to leave the club on a free transfer, with Branislav Ivanovic and Paulo Ferreira currently the Blues' only senior right backs.

The 22-year-old started his career at Osasuna before moving to the south of France in 2010, and helped Marseille to the Coupe de la Ligue in consecutive seasons.

But he has found his international opportunities limited, missing out on a Euro 2012 call up with Real Madrid defender Alvaro Arbeloa preferred.
