The goalkeeper had been sidelined since Jan. 23 after he fractured a bone in his left hand during Los Blancos' Copa del Rey quarterfinal victory over Valencia. The Spain international resumed ball training on Friday, though, and has now been deemed fit enough to participate in the second leg of his side's round of 16 European tie at Old Trafford.
Elsewhere, defender Nacho will join up with the rest of the squad late due to the 23-year-old having to prepare for the Castilla team's Segunda Division clash with Ponferradina later on Sunday.
Real Madrid squad to face Manchester United: Casillas, Adan, Diego Lopez, Jesus; Ramos, Arbeloa, Marcelo, Albiol, Varane, Pepe, Coentrao, Carvalho; Modric, Alonso, Khedira, Ozil, Kaka, Callejon, Di Maria, Essien; Cristiano Ronaldo, Benzema, Higuain, Morata.
