Real Madrid won the La Liga title four rounds in advance, and coach Ancelotti became the coach of the five top league champions of West, Germany, England, Italy and France, and suddenly the outside world's pursuit of Ancelotti was incomparable.

Winning a Grand Slam in five leagues is something to celebrate for any coach, but that doesn't mean Ancelotti is the boss in the football coaching charts. Looking back on An Shuai's coaching career, it can only be said that his giant fate is particularly deep, but in terms of the ability to lead a team of average strength or long-term decline to complete the counterattack, he is really inferior to Mourinho and Klopp.
In fact, Ancelotti's coaching trajectory is similar to Guardiola's, he has been wandering in the big club, and the cards in his hand are inherently better than others. When Carlo Ancelotti won the top five league titles, he coached Chelsea in 2009/2010, Paris in 2012/2013, Bayern in 2016/2017, AC Mi in 2003/2004 and Real Madrid in this season.
It can be seen that these five teams were all strong in their respective leagues at that time, especially Bayern and Paris, and winning their respective league titles was almost a script written in advance, and it did not matter who was the coach. This season, because Barca is in the reconstruction stage, it is not difficult for Real Madrid to win the championship in La Liga, and when he coached Milan, it is not to say that there are a lot of stars in the team. The only challenge was at Chelsea, when they snatched the Premier League title from the old man Alex Ferguson.
Carlo Ancelotti has been playing downwind games since the moment he was in charge, and so has Guardiola, whether at Barca or Bayern or now Manchester City. Mourinho and Klopp are different, they both climb up in the slightly less powerful team, and sometimes come out of extremely difficult adversity.
Think that year, Munirio can lead Porto and Inter Milan to win the Champions League, it is unprecedented, no one has ever done, Ancelotti led Real Madrid to win the Champions League and the Copa del Rey in 2014, first, because the team lineup is luxurious enough, and second, Mourinho left a tactical legacy. Prior to this, Mourinho had been playing against Barca and then winning, and if it had been Mourinho in the 2013/2014 season, Real Madrid would have won the treble.
Klopp's original bundesliga team against Bayern in Borussia Dortmund and the ability to win two consecutive Bundesliga titles was not easy. In the 2012/2013 season, Klopp led Dort to the Champions League final, which Ancelotti certainly could not do. After coming to Liverpool, Klopp promised to win a title within five years, and as a result, others not only took it, but also took it in advance, and the Champions League, the League, the Super Cup, and the Club World Cup were all won. The main thing is that Klopp has brought the reds the first Premier League title in the history of the team, can Guardiola and An Shuai do this?
