Diego Costa has received permission to negotiate a move to Atletico Madrid instead of joining Chelsea for the start of pre-season training.  Costa was absent at the club’s Cobham training base. The La Liga side has offered around £26 million for Costa’s signature, but Chelsea is not willing to sell for that figure, and negotiations will reportedly continue through the week as a result. Should a deal fail to materialize, Chelsea boss Antonio Conte – who told Costa via text message that he wouldn’t be a part of his plans for the upcoming season – will need to decide if Costa will travel with the club next Monday for its pre-season tour of China and Singapore.
