Real Valladolid boss Juan Ignacio Martinez has admitted that his side will have to be at their best to overcome Real Madrid in La Liga this evening.
Victory for Valladolid would move the strugglers out of the relegation zone, but Los Blancos need the points to continue their title challenge.
"We face a great team. They're finalists in the Champions League. That comes from playing good games and not stumbling at home," Martinez told AS.
"All coaches say that to win you have to be immaculate, perfect. They're not perfect but they have great resources. We have to make as few mistakes as possible.
"Their two lethal weapons are counter-attacks and set-pieces. They give you limited opportunities because they can dominate the game."
The reverse match this season ended in a 4-0 Madrid win.
