Unai Emery believes Valencia still face a tough task against a Real Madrid team likely to be focusing on the Champions League.Real will visit Valencia's Estadio Mestalla on Saturday for the second time in four days following their victory over Barcelona in the Copa del Rey final last Wednesday.

But the La Liga meeting with Valencia is sure to be low priority for Real, who are preparing for an all-important Champions League showdown at home to Barca on Wednesday.

Nevertheless, Valencia coach Emery believes the visitors could still pose a serious threat in the match between La Liga's second and third-placed teams.

"Real Madrid will be very dangerous, especially if those who did not play on Wednesday play," Emery said.

"It will be a duel where motivation will be at the maximum."

Emery believes Mourinho is likely to rotate his players - adding an element of uncertainty to his own tactics.

"At the time of preparing this game it would be easier to know which players will play and how," Emery said.

"Madrid have a defined way of playing football and I don't think it will change much. It's not the same as to whether Cristiano Ronaldo is there or not.

"There are differences between Gonzalo Higuain, Karim Benzema or Emanuel Adebayor."

"We know they have distinctive characteristics and they are dangerous on the break. They are a great team, but we must learn how to handle them."
