Saying Real madrid is the best team in Laliga is an underestimation, they are probably the best in the world right now.
There is nothing wrong, Real Madrid will be the best team in La Liga and Europe in the 2023-2024 season. They won the La Liga title and the Champions League, but to say they are the best in the world is probably a bit of an exaggeration in my opinion. La Liga is not competitive at all in the 2023-2024 season, the rivalry doesn't really exist because Barcelona and other teams are not in good form.
It's not because they have won the highest number of champions league or domestic league but because of the performance they display whenever they play games. They play collectively and not relying on a single player. We thought the team performance will depreciate after Ronaldo left, the same thing when Benzema left but surprisingly, the young players currently in the team make it to be more stronger than it was before during the era of their legends who left. They recently signed Mbappe finally after rumors for several months now, it's indeed an addition to Real madrid and will continue to dominate football for seasons to come.
Real Madrid's performance last season was very good with only 1 loss and 8 draws in 38 La Liga matches, I have to admit. They have a lot of money to invest in players, which clearly supports the coach's plans to win the title. But behind all that, there are teams that are losing competition due to financial problems and poor team performance throughout the season.
Next season will be easier for Real Madrid. Real Madrid can be expected to win the La Liga title easily, but it is still difficult to expect them to retain the Champions League title even though the main squad is really high quality.
