Chelsea manager Jose Mourinho has once again reiterated that he does not know whether star striker Diego Costa will start in the club’s first game against Swansea City this weekend, according to the London Evening Standard.
Costa was unavailable for selection when the Premier League champions played Arsenal in the Community Shield on Sunday after sustaining a hamstring problem when the Blues faced Barcelona in a pre-season friendly.
And his absence saw Chelsea succumb to a 1-0 loss to the Gunners, which was Mourinho’s first ever defeat to Arsene Wenger in 14 games.
Despite being rested, Mourinho is still unsure of the Spain international’s condition, but revealed that Costa is working extremely hard to be fit ahead of their season opener.
“The only thing I can reassure about it is that he is working hard,” Mourinho stated.
“He was not ready for the Community Shield but everybody around him is working to help him.
“I do not like the word concern because I have other players. It is not my way to be complaining about players who do not play.
“In such a small squad like we have, when someone is missing I am not happy but I will not complain.”
The 26-year-old missed the tail end of their title-winning campaign with the same hamstring issue, but his efforts earlier last term saw the Blues in good standing before claiming the title.
The former Atletico Madrid hitman’s injury concerns saw him only make 26 league appearances, but still scored 20 goals.
