Costa said that his pressing concern at the moment is trying to win La Liga and the Champions League with Atletico, before he even discusses the possibility of a transfer.
"I feel good at Atletico, I am happy in Madrid," Costa told Sky Sport Italia. "We will see what happens, there are offers but it is too early yet to talk.
"Now I am just thinking about the end of the season, I want to win the Champions League and La Liga."
Costa now represents Spain at international level, despite previously making two appearances for his nation of birth, Brazil.
