Atletico Madrid midfielder Mario Suarez has admitted that his side will have to be at 100% to overcome Real Madrid in the semi-finals of the Copa del Rey.

Diego Simeone's team travel to the Bernabeu for the first leg on Wednesday in a repeat of last season's final, which Atletico won 2-1.

"They are totally different competitions. We've done our job today and Wednesday is a nice tie in a competition in which we defend the title against arch-rivals," he told reporters.

"We return to the Bernabeu. It will be a very nice game and we will do the things we do to try to get a positive result. The important thing is that we are all 100%."

Atletico currently top La Liga by three points.
