Chelsea striker Diego Costa unsettled in London, according to Spanish sources.

Marca says Costa recently met with Atletico chief Miguel Angel Gil Marin during a visit to Ibiza.

It's suggested Costa has told his former Atletico team-mates he'd like to return to the Vicente Caleron and Angel Gil spoke to super agent Jorge Mendes about the possibility of a deal.

However Mendes played down the chances of Costa leaving Chelsea and the Spaniard's wages are thought to be a major stumbling block in the deal.
