Real Madrid manager, Carlo Ancelotti, senses a potential banana skin in the form of promoted Elche.
Los Blancos travel to Alicante to face the minnows in La Liga on Wednesday night, having dropped just two points so far this season.
The hosts meanwhile, are finding life in the upper echelons a slog, and have just three points to their name.
Madrid have been on fire of late, scoring goals for fun in Spain and in Europe, and Ancelotti accepts that the firepower at his disposal is the stuff of Elche dreams.
But shocks do happen in football, and he has warned that Real will have to be at their sharpest to avoid an embarrassing result tonight.
"It will not be easy," he said.
"Every match, before the game you have to stay focused, stay concentrated.
"Of course we have to consider that we have more quality but if we don't use the same motivation, the same character of the opposing team, it will be difficult.”
Meanwhile, Gareth Bale remains out of action, having picked up an injury last weekend. He should be available to play in the Madrid derby in a few days, however.
"Bale trained apart from the rest of the squad and I think he will be ready for Saturday no problem," Ancelotti said.
"He won't be available tomorrow but we have time to train with him to prepare him well for Saturday."
