Atletico are now above rivals Real Madrid on the La Liga table.
“Now we are already looking ahead to beating Espanyol in order to achieve our aim of finishing the year among the top four. We can do it,” Aguirre told reporters.
“This win was very important. Betis played well and they have a history of picking up points here.
“They are not an easy side to beat, but the team played very well in the first half. In the second half we left too much space and let them have the ball, but we were able to finish the game.
“The team handled things well. It was important not to concede because that is the basis given our attacking potential.”
