FC Barcelona projected XI: Bravo, Alves, Piqué, Mathieu, Alba, Busquets, Rakitic, Iniesta, Neymar, Messi, Suárez.
Real Madrid projected XI: Casillas, Carvajal, Pepe, Ramos, Marcelo, Kroos, Modric, Isco, Bale, Ronaldo, Benzema.
Sergio Busquets is the only questionable player out of those 22 men. The midfielder has made Luis Enrique's list but he just recovered from a muscle injury.
On the other hand, Carlo Ancelotti will need to decide his formation, because he will not make any surprising calls on his starting XI. Real Madrid will most likely play under a 4-4-2 with Isco and Bale providing much needed help on the wings. That's the same tactic that proved to be successful last October, when his team defeated FC Barcelona 3-1, though it's true that James Rodríguez played on the right wing and replaced Bale, who missed the match with an injury.
