Atletico Madrid defender Mario Hermoso says the players are confident Diego Costa will rediscover his best form.
Atletico are at Champions League opponents Bayer Leverkusen tonight.
Hermoso said, "The team is united, we are demanding people and the things that are heard do not affect us. We know how our way of working is and we believe in it, that is important.
"We know how important he (Diego Costa) is. He does not have the fortune of the goal but will find it. He is a winner, he is one of the most important in the group. He is not happy and sure his goals will come soon."
