The Rojiblancos boss says his side can only match Spain's finest over one match, rather than a 38-game season, after watching the Blaugrana claim the Supercopa.
Gerardo Martino's men claimed the first silverware of the season on away goals, with Neymar's first-leg strike in a 1-1 draw proving the difference after a 0-0 stalemate at Camp Nou. And Simeone believes his side can only match Spain's top teams over 90 minutes, not over a 38-game season.
"Barca are better than us, Real Madrid are better than us," he told reporters after the game. "Their economic strength puts them out of our reach. In a one-off match we can try and match them, but not over a league season."
Atletico had two players see red over the course of the match, with four others picking up bookings, but Simeone went on to defend his side's approach.
"It’s normal for there to be contact in football," he said.
