Therefore, I have never been surprised at all by Real Madrid's approach to building their squad. They have 17 foreign players in their squad and are the second team with the most foreign players in La Liga after Sevilla. I wouldn't be at all surprised that Real Madrid could win the La Liga title in so many seasons, but would only be surprised if they were thwarted by their two closest rivals.
Real Madrid really has a solid squad and in my opinion they have the healthiest finances among their two competitors in La Liga, Atletico Madrid and Barcelona. So I also agree that they deserve to win the title again next season.
The more success, the more income. This is exactly what can happen. Real Madrid has earned very high revenues in recent years, both as success awards and viewing awards. Of course, the reason for these successes is that they offer high contracts to players and high limits. Players also have extra income through sponsor agreements. I am almost sure that Mbappe will earn high income from jersey sales.
I think Real Madrid has really become a special club. Not only do they have healthy finances and a good club history, but they have also been a club that has had large revenues in recent seasons due to their success in La Liga and the UCL. Not many clubs have had success like Real Madrid.
