Atletico Madrid President Enrique Cerezo expects the team to give their all in trying to beat Real Madrid on Tuesday.
The sides meet at Vicente Calderon in the second leg of the Copa del Rey semi-final with Los Blancos holding a 3-0 lead from the first meeting.
But Cerezo told reporters he believes Atleti will do everything in their power to overturn the score.
“We’re going to fight till our last breath to try and turn that result around,” Cerezo said.
“It won’t be the first time we score three against Madrid, and it won’t be the first time they beat us at our ground.
“It’ll be a great game to watch, played eye to eye and is now delicately balanced.”
Cerezo was also asked about the standard of refereeing in Spain after a number of controversial decisions in recent games, including Atletico’s defeat to Almeria on Saturday.
“It’s very difficult for referees. The other day he could have made a mistake but sometimes mistakes go your way and others they go against you.
“Our problem is that we lost a game because maybe we didn’t play well, it was very windy or things like that which affect the normal progress of a game.”
Diego Costa will miss the Cup match after he was booked in the first leg and Cerezo suggested that more alert refereeing would spot that the forward is the victim more often than not.
“It’s a great for Spain that he’s with the national squad, on many levels,” Cerezo began.
“He takes more hits than he dishes out and that’s all there is to say.
"Due to circumstances there are times that, from one point of view or another, you see it more or less.”
