Rayo Vallecano coach Paco Jémez believes his team will be able to create scoring opportunities against Real Madrid at the Santiago Bernabéu on Sunday.
The Vallecas side beat neighbours Atlético Madrid 2-1 last Sunday and Jémez is hoping for a similar result against Real.
"I think we will have our chances at the Bernabéu," he said in an interview with television channel 'Cuatro'.
"It's a big pitch and if you are brave and have the ball, you can leave with the prize," he added.
Jémez also spoke about his opposite number on Sunday, José Mourinho, a man who he said "has to be made of stern stuff to be able to stand the pressure he is under".
"Everything he does has global repercussions," he said of the Madrid coach.
"His future will have a bit to do with what happens in the Champions League. Anything can happen, he could win the Copa del Rey and the Champions League and that would consolidate him as what he already is: one of the best coaches in the world."
Jémez attended the Manchester United game at the Bernabéu as a special guest, and was photographed waving a small Real Madrid flag before the game.
He explained his actions: "When you arrive at the box you find your seat and you find a little Real Madrid flag there. You can do two things - either you pick it up, or you sit down and you get it stuck in your arse. I went for the first option."
