Diego Costa has taken to social media to reveal that he was all smiles in the build-up to Chelsea’s Premier League clash with Hull City on Sunday.

The Spanish striker’s situation has been a relentless source of speculation in recent days amid reports that the forward had a falling out with Chelsea coaching staff at Cobham.

Costa sat out last weekend’s 3-0 win over Leicester City at the King Power Stadium but Antonio Conte confirmed on Friday that the striker would be fit and ready for the Blues’ clash with Hull on Sunday.

And the forward seemed to be in good spirits in Chelsea training as he posted the picture above on his personal Instagram account and wrote the caption: “Come on Chelsea!!!⚽️😄👍🏽”
