I would say that Real Madrid are not very interested in La Liga matches at the moment. They have a decent point lead over second-placed Barcelona in the table. And winning the La Liga title is not a difficult task for Real Madrid now.
So maybe Real Madrid will now try to perform well in the Champions League. The Real Madrid team will face the powerful Manchester City in the Champions League. And it is very difficult for Madrid to beat Manchester City. Even most of the gamblers are considering Manchester City as the favorite in this match.
Real Madrid will play against Athletic Bilbao, Mallorca and Barcelona in the next three matches in La Liga. Although Real Madrid is a strong team, they are likely to drop points in these three matches. Because Madrid's main goal is to perform well against City. So Madrid probably won't give full effort in these three matches.
It's true that Real Madrid is already 8 points ahead at the moment, but they can't be too dismissive and think they will easily win the La Liga title because there are still 10 matches left in this season which makes anything possible and even Real Madrid still has several difficult matches left. including against their rivals Barcelona.
Real Madrid will definitely be distracted by the UCL match against Manchester City, but I am quite sure that a team as big as Real Madrid will be able to prioritize both equally without leaving anyone out because both are very important to them.
I am sure that the match between Real Madrid and Manchester City will be of very high quality because both teams are fighting very well and their player quality is at a high level. There will be a fight between two world-class teams. It is lucky for us that this match will be played twice.
