Ahead of the crucial game Jose Mourinho and Pep Guardiola have both engaged in a war of words, Pep has said that the Portuguese manager is the king of mind games, Pep also pointed to the fact that the first leg may go against them because the referee who is in-charge is from Portugal and may favor the home because because Mourinho is also from Portugal.
"He spoke directly to me, so I'll do the same to him. Tomorrow we'll take to the pitch at 20:45. Off the pitch he's beaten me," Guardiola said.
"In this room [the press area] he's the f***ing chief, the f***king boss, and I can never compete with that.
"It's the kind of game that I won't play because I can't do it."
"I won't justify my words, either," Pep added, this will be the third El Classico in a month and Real have an edge because they are playing at home and they beat Barcelona in the final of the Copa del Rey.
"I congratulated Real Madrid - they deservedly won the cup on the pitch against a team that I represent and that I'm proud of. I didn't put that down to the referee. I've never done that."
"On the field I try to learn a lot when I play against him. Off the field, I try to learn little. You can play in many ways - the method he uses is very good."
Andres Iniesta will not play in this crucial match and Pep also said that the player will be a big miss.
"Andres Iniesta is injured. I could tell you he is 80% certain to be out, but I am saying he is 100% out. He will not play."
Pep said that Puyol, Fontas or Javier Mascherano will replace the instrumental midfielder, "Puyol, [Javier] Mascherano, [Andreu] Fontas, whoever is suitable. What is certain is that we'll line up with eleven men."
