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.
Real Madrid has a 100% chance of winning the Liga this season because there isn't a team with more points than them; they are ahead of Barcelona and Girona with significant leads, and their actual performance is still looking good. Ancelotti will ensure that Real Madrid wins the Liga this season. Barcelona's performance in the Champions League, which got them to the quarterfinals, is making them happy and even thinking that they can win the title again. In my opinion, it would be better for Barcelona to play in the Champions League, even though they can't advance to the finals.
Real Madrid and Manchester City are playing in the quarterfinals of the Champions League. Many people believe that Manchester City will defeat Real Madrid in the same manner as they did the previous season, but I can guarantee that if Real Madrid plays with seriousness, they will win. Real Madrid has talented players who can easily take down Manchester City, and their performance this year has also changed from last year's, so I'm very confident that Real Madrid can win Laliga and still defeat Manchester City in the Champions League.
