Atletico Madrid striker Fernando Torres has called on fans to lift the atmosphere after victory over Alaves.
Torres proved the matchwinner on Saturday night.
He said, "We must rediscover the Calderon atmosphere in a much bigger stadium.
"Fans are starting to get more involved, but the quiet is much more noticeable here.
"It's only a matter of time before this changes, it's now up to us to fill this stadium with memories and titles."
Saturday's victory puts Los Rojiblancos to within three points of Barcelona, although the Catalan giants are in action on Sunday against Deportivo La Coruna.
"Atletico are now second," he continued.
"This is where we want to be and that's important."
