Jose Mourinho has revealed Diego Costa is yet to properly train with his Chelsea teammates, despite scoring his eight of the season on Saturday.
The Portuguese manager confirmed the Spaniard still has a hamstring injury that is limiting his involvement in training.
Mourinho said: “He cannot be on top of his game, but even so scoring a goal is good for his confidence.
“He’s doing almost nothing in training. He’s just resting and recovering from the tight muscle he has. Every time he accumulates fatigue.
“But I don’t care about Diego’s goals. For me it’s important that the team score enough goals to win
“I know a striker scoring goals is always nice for him and for his confidence.
“Especially for a player like him who is not training as he should, because we are protecting him in certain situations.”
The Blues’ boss also fears his main man could risk a hamstring tear if he links up with the Spain squad for next month’s matches with Slovakia and Luxembourg.
Mourinho said: “If he doesn’t go to the national team and if he stays here 15 days just on treatment, he has the perfect chance to be top for Chelsea and top for the national team.
“If he doesn’t have this period, will be always, plays one game, the other is in trouble, the muscle is tight, the muscle is danger to rupture.”
