Real Madrid boss Carlo Ancelotti admits he may persist with Sergio Ramos in midfield.
Ancelotti used Ramos in midfield for victory over Atletico Madrid in the Champions League.
"It's an option, he did very well, but I have other options in central midfield," said Ancelotti.
"There's also Isco, I have several options in this position and I'll decide tomorrow. Ramos is a player with experience, and he can play in midfield thanks to that. He's going to help the team whether in central defence or in midfield."
