Carlo Ancelotti faces some crucial selection decisions ahead of Real Madrid's derby clash with Atletico Madrid tomorrow night.

Los Blancos now sit just one point clear of their city rivals at the top of the table, and the title race could be set for another twist this weekend.

Ahead of the clash with Atletico Madrid and two UEFA Champions League games against Manchester City, Ancelotti is meticulously planning his approach, with injuries a constant concern.

Defensive lynchpin Antonio Rudiger will miss the Atletico Madrid game and the first leg at City, but the Germany international remains hopeful for the return leg.David Alaba, who recently returned to action, has been injured again and is expected to be out for 2-3 weeks.

Ancelotti rotated the inexperienced duo of Jacobo Ramon and Raul Asencio in the centre of defence for the 3-2 Copa del Rey win over Leganes in midweek.

Asencio has been used by Ancelotti this season, but it was a first start for Ramon on a nervy night for the 20-year-old, who also conceded a penalty.

Tchouameni has been told not to get "too comfortable" in midfield at Leganes, an indication of Ancelotti's intentions, but Ramon will not be involved as the Italian wants to over-expose him.

“He paid for it a little on his first start with us, he was nervous. They are ready-made players, but they obviously lack experience,” as per quotes from Relevo.

“Although Jacobo grew into the game, and finished the match fitter, he still needs to improve at Castilla before facing big teams at the level of Atletico or City.

“Jacobo is a very good defender, we will count on him, he will be with us for the rest of the season. He will play better than at Leganes, I’m certain, he is a very good player.”
