Diego Simeone has revealed his side, Atletico Madrid will not underestimate copa del rey opponent, Reus Deportiu on Thursday.
Atletico hold a 2-1 win over Reus, but are on alert for a possible upset.
And Simeone believes they can overcome their opponents.
“We’ll go with everything we have, as always, and with what we understand will make us continue in this Copa del Rey – which, as we’ve always said, we respect because it’s given us many joys and because Atletico Madrid is historically a cup team,” Simeone told reporters.
“It is tight – 2-1 is not a 4-0 result and it’s clear that dangerous situations can always happen in football. You have to be ready so they don’t happen.
“The best way to be prepared is to do your best, try to respect the rival that played a good match in the first leg and that has good qualities – especially the speed of the guys at the top who made the first-leg match complicated for us.
“We hope to solve it well and to be as strong as we have been lately.”
