Diego Costa wanted to leave Chelsea in the summer

Diego Costa admits he tried to push through a move back to Atletico Madrid before eventually going to Chelsea boss Antonio Conte with his "tail between his legs".
The striker was heavily linked with a move back to his former club last summer after enduring a frustrating 2015/16 season as Chelsea failed miserably to defend their Premier League crown.
The two clubs were reportedly in negotiations over the transfer but talks broke down, which meant Costa had to build bridges with Conte
