Chelsea boss Jose Mourinho is resigned to losing Diego Costa to Spain next week.
Diego Costa is carrying a hamstring injury.
Mourinho does not expect Spain to respect his wish not to call up Costa for national service.
The Portuguese said: "I have the feeling that next week he goes to the national team. I have the feeling that in the national team they will not consider the fact that he is in trouble so tomorrow he plays and hopefully he plays Sunday again against Arsenal.
"But in this moment I don't think about Arsenal - I think about Sporting. And Diego starts tomorrow."
