Mourinho announces his starting line-up one day before the match kick-off.
The following is the Real Madrid squad announced for the Copa Del Rey Final:

Keepers: Casillas, Adán, Dudek
Defenders: Carvalho, Pepe, Sérgio Ramos, Marcelo, Arbeloa, Garay
Mid-Field: Kaká, Granero, Xabi Alonso, Ozil e Khedira.
Attack: Adebayor, Cristiano Ronaldo, Benzema, Higuaín, Di María

In a recent poll on spanish newspaper Marca, Madrid supporters have voted for sacrificing Benzema in turn for solidifying the defensive midfield with Pepe being the likely candidate to play in front of the back four to stifle the Barcelona attack. Jose Mourinho has stated that Madrid will defend with all 11 players when Barcelona have the ball - that´s if Madrid don´t have any players sent off.

Ozil is also prefered by the supporters to start. Ozil's presence in Saturday's match was the driving and solidifying force for a 10 men Madrid who managed to claw back a goal and save a humiliating loss at home to their biggest rivals.

The starting 11 most voted for by 37% of the supporters:

Casillas
Ramos, Arbeloa, Carvalho, Marcelo
Pepe
Khedira, Xabi
Ronaldo, Ozil, Di Maria

The following players were noticeably absent from the selected squad: Lass (injured), Gago (injured), Pedro Léon (coach decision) and Canales (coach decision), Albiol (suspended).
