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.
Real Madrid is the team that most consistently maintains its performance every season, every player brought in is able to contribute well and immediately blends in with the fast and sharp style of play that has been the hallmark of Real Madrid game. One of Real Madrid successes in winning many titles was because the players supported each other in achieving the club's goals, they showed classy play with very collective teamwork.
Losing Ronaldo and Benzema did not really affect the team's performance, without these two players they were still able to prove their quality as the best team in the world. Now that Mbappe is starting to be included in Real Madrid squad for next season's competition, the combination of Bellingham, Vinicius and Mbappe will make it increasingly difficult for other teams to beat Real Madrid. As you said, maybe Real Madrid will continue to dominate for the next few seasons because the players they currently have are still young.
