Diego Costa has declared that he is happy at Chelsea.
The Brazilian born Spanish international striker had been linked with a return to Spain last season.
Costa said: “Mourinho is a big coach and for me it was decisive when I spoke to him about joining Chelsea.
“He explained his objectives and the project in the squad and that was definitive for me.
“I am very happy at Chelsea. The rumours about me and my future are normal but they are of no interest to me.”
