Cesar Azpilicueta remains a key target for Barcelona this summer, but Chelsea's valuation of the defender is proving problematic.
Azpilicueta has agreed personal terms with Barcelona which would see him receive a significant pay rise, but Chelsea want a fee of £7million for him, as reported by goal.
Barcelona have already brought in one defender from Chelsea in this transfer window, with Andreas Christensen joining following the expiry of his contract with the Blues.
Azpilicueta had also entered the final year of his deal at Stamford Bridge but an automatic one-year extension was triggered in March when he had made 35 appearances last season.
