Winning the La Liga title is not difficult for Madrid. Real Madrid is not ahead by a big margin. However, Madrid's two main opponents, Barcelona and Girona, have had erratic performances. That's why it won't be difficult for Real Madrid to win the La Liga title. So Ancelotti will now prepare his squad to face Manchester City.
Ancelotti can prepare his team for both Manchester City and their games in LaLiga, the LaLiga is not over and they would want to win the two tournaments and not one. I don't agree that winning the LaLiga is easy for Real Madrid, if they make mistakes and start to drop points, Girona and Barcelona would be there to take advantage of it. Real Madrid is a team with so much quality, they don't have to drop their performance in any tournament, they can play at their best in the both of them and win it.
