Ancelotti takes full Real Madrid squad to Copa del Rey final
Carlo Ancelotti has offered no clues as to who may start against Osasuna and has called up all 23 first-team players, plus 21-year-old Luis Lopez.
Even Ferland Mendy, whose fitness has been a question mark for some time, has been included.
The Frenchman has only played 29 minutes - 19 in March's Clasico in La Liga - in the last three months, and has been out since the beginning of April.
Also present is Luka Modric, who will likely face a late fitness test, despite progressing well from his physical problems.
It could be one of the Croat's last chances to win a trophy in Los Blancos' shirt, if the rumoured signing of Jude Bellingham for next season is confirmed.
Real Madrid's squad
Goalkeepers: Courtois, Lunin and Luis López.
Defenders: Carvajal, Militão, Alaba, Vallejo, Nacho, Odriozola, Lucas V., Rüdiger and F. Mendy.
Midfielders: Kroos, Modrić, Camavinga, Valverde, Tchouameni and D. Ceballos.
