Squad trains with sights set on Ludogorets
Ancelotti included Castilla player Medrán in the penultimate session before Wednesday's Champions League match.
He is the team's first ever player to score 10 goals during the opening six matchdays.
Butragueño attended the announcement of the friendly, which will be played at The Sevens Stadium.
It will be the second time the Scottish official takes charge of a match involving the Whites in the Champions League.
Real Madrid beat Barcelona to claim the first trophy of the season in a final they dominated from start to finish, with tournament MVP Llull in sensational form (21 points).
"The aim was to win here and we're happy with the victory," said the man from Menorca.
Sergio Rodríguez was also among the award winners.
