Real Madrid face rivals Atletico Madrid in La Liga on Sunday.
Mourinho remarked: “Atletico have a young goalkeeper who, unfortunately for me, is like Iker Casillas.
“Who will play? The starters today could be substitutes tomorrow and vice-versa. It’s the group that counts, and this is what makes it easy to be the league leaders.
“My teams don’t play to win derbies, they play to win leagues and titles, and to win the championship you need to win games and points.
“I want to win tomorrow because we want the points, not because we are playing Atletico or because it is the derby.
“We want to win, it will be a tough game, but we have to be at our best.”
