Real Madrid have been in massive form this season. Carlo Ancelotti has guided his side to an unbeaten stretch of 21 games.

The last time Real lost a game was against Atletico Madrid, in a La Liga clash back in September.

Ahead of meeting same opponents, Carlo Ancelotti has revealed the secret to Madrid’s unbeaten run: “I like the atmosphere at this club and in this dressing room.

“The key to success is the calm atmosphere, a motivated group and a strong team spirit. We also play good football, we’re solid and have clear ideas.

“These are the three components that enable you to be successful: a motivated atmosphere, a strong team spirit and playing good football.

“If we don’t win the derby tomorrow, we’ll come down from that cloud. Danger comes when you don’t get what you want. You have to be ready for that and prepared.

“It’s a very good run and I don’t ‘t know when it’ll stop, but it will. We can’t win every game. When it does, we have to get out of it quickly.”
