Diego Costa could have given a huge clue that he will be in the squad to face Swansea after being snapped taking part in training on the eve of the club’s Premier League opener vs Swansea.
The Spanish international had been rated doubtful ahead of the game with a recurrence of the hamstring problem that dogged him for much of last season.
Scoring 20 goals in 26 appearances, the club will be hoping he’s able to be on firing form over the next nine months, starting with the clash vs the Swans this weekend.
