Saying Real madrid is the best team in Laliga is an underestimation, they are probably the best in the world right now. 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.
In my opinion, what makes Real Madrid worthy of being called the best team in the world is because they show how impressive their performance and winning mentality are. What makes Real Madrid so good in my opinion is that they always manage to escape the pressure after experiencing bad results. They are playing very well in La Liga with only one defeat. They play collectively as a team and therefore I think they will not have a problem if any of their players choose to leave Madrid.
The number of trophies is of course a benchmark for determining whether the team is the best team in the world. You cannot say that Real Madrid is the best team in the world just because of performance. After all, because of such good performance, the result is about winning many trophies. So still, basically winning the most trophies is the main benchmark for Real Madrid to be called the best team in the world. Apart from that, Real Madrid always has great players and/or star players every time regeneration occurs, so Real Madrid always has star players and great players in its squad. Therefore, of course it is very appropriate for Real Madrid to be called the best team in the world because they have lots of trophies and also always have luxury players in their squad.
