Atletico Madrid president Enrique Cerezo has claimed that Rojiblancos and Barcelona are currently the top two teams in world football.
The pair meet in the second leg of their Champions League quarter-final on Wednesday, with the score currently level at 1-1 from the first leg last week.
"Atletico will play a superb game, we're going to do great at the Vicente Calderon," Cerezo told Cope.
"If we get through then we will surely face Real Madrid at some point. On Wednesday, the two best teams in the world will play in Atletico and Barca."
Atletico currently lead the way in La Liga, one point ahead of Barcelona with six games remaining.
