The agent of Chelsea star Juan Mata has offered the former Valencia man to Spanish Liga clubs. The Sunday Times says Mata's representatives have been in contact with Atletico Madrid and Barcelona about a move this month. Napoli and Inter Milan have also been contacted.

Mata is becoming increasingly concerned at Chelsea over his place in Vicente del Bosque's Spain World Cup squad. He knows he needs to be playing to be sure of being on the plane to Brazil this summer.

This season under Jose Mourinho, Mata has played only three full games for Chelsea.
