Costa has scored 10 times in eight league matches this season, with Atletico claiming 24 points from a possible 24 thus far.
"We hope to keep Diego Costa dry, I really trust in my defence. We know that he is one of the best players and that he will be hard to stop. He is a tough forward, who blows away opponents," he told reporters at a press conference.
"He does not stop pressing, he has great quality and always plays with great intensity."
Costa had been linked with a move to Liverpool in the summer before penning a fresh contract with Diego Simeone's side.
