The former Atletico Madrid attacker is confident of upsetting Real.
"We are going into the game on the back of a good run. It's difficult, because we're facing quite a strong opponent, but we have our weapons. We must have confidence in ourselves," he said.
"As well as that, we are playing at our ground with the support of our fans and we have to go out and give it everything.
"We know that it is complicated to win. Last year they got the three points here and we have to learn from that defeat. We need to think that it's 11 players against 11 and hopefully they won't do so well at the Coliseum."
