But they know that have a moerse challenge on their hands if they are to overturn the 3-0 pak they got from bitter rivals Real in the first leg last week in tonight’s return at the Calderon (8.45pm).
Confidence is soaring at Real as they remain on track to win the domestic title and all signs point to the 11-time European champions piling more misery on their neighbours who they beat in the 2014 and 2016 finals.
But Atleti coach Diego Simeone was typically defiant ahead of the clash.
He says: “On Wednesday we have an extremely difficult game which for some would be impossible, but not for us.
“After the last game I told the players it was very tough, that we’re facing the best team in the world that scores in every game but we can do it. I’m convinced we can, if I wasn’t I wouldn’t say so.”
Captain Gabi, meanwhile, is taking inspiration from Barcelona’s record-breaking comeback from a four-goal deficit against Paris St Germain this season.
He adds: “Of course we can do it, look at Barcelona, and they had an even more difficult result,” he said.
“We’re convinced we can do it, we’re going to fight for it and if not we can at least go out with our heads held high.”
