Real Madrid boss Carlo Ancelotti expects a big challenge against Valencia today.
Los Che are being revived under coach Nuno this season.
"It's a very important game, because we'd like to continue the run we're on and stay top of the table. It's a very, very important match. Playing away from home against Valencia is very difficult and it would be great to get the win.
"The game against Valencia is a difficult one in which we need everything. We'll need to defend and attack well. They're a team who have totally changed their style from last year. They're stronger and more solid. It's a very difficult match. They've shown that they're a very dangerous team at home."
