Cesc Fabregas has claimed that Jose Mourinho has an "edge" over Arsene Wenger and Pep Guardiola when it comes to winning and is the best manager for whom he has played.
Chelsea won the Premier League on Sunday, meaning Mourinho averages a trophy every 34 games in his managerial career and has won eight championships in four countries.
This was the first time Fabregas has won the Premier League, having lifted the FA Cup with Arsenal and La Liga and the Copa del Rey at Barcelona.
Wenger, like his Chelsea counterpart Mourinho, has won three Premier League titles with Arsenal. Guardiola secured three La Liga titles while he was in charge at Barcelona and has won the Bundesliga twice with Bayern Munich.
Fabregas said of Mourinho: "He just loves winning. I'm not saying other managers I have played under don't, but he has some edge that goes above anyone else I have ever been with. The mentality he shows in every single training session, or game, I now understand why he has won what he has won in his career. He's the best manager and he has to get results and he always manages to do that."
Asked whether Mourinho had a magic touch, Fabregas replied: "Yes, 100pc. He knows how to manage a team, he knows how to get the best out of you and that's what you want from a manager. A manager that can motivate a player every three days, when you play 60 games a season, it is not easy. Trust me.
"Everyone thinks that we have a big squad, but we don't, 22 players, and some of them are from the academy, and U-21s. So it's not easy. He actually is doing a fantastic job."
In terms of his club career Fabregas, who has won the World Cup and European Championship with Spain, rates the Premier League success this season as one of his top three achievements in - which Arsenal do not feature. "This (Chelsea's title win) is in the top three for sure," he said.
"Winning the title with Barca, getting 100 points with Barca was amazing, I played 36 games then, I played 32 games here, champions, so obviously you feel important and that's what you want as a player. You want to feel part of it and that's what I'm doing at Chelsea."
Fabregas was handed the responsibility of giving the dressing-room speech to the Chelsea squad ahead of the Crystal Palace game and he could be in line to take over the vice-captaincy if, as expected, Petr Cech leaves in the summer.
Fabregas, who turned 28 yesterday, is one of the more senior players in the squad and he believes that the team can win plenty more silverware together.
He said: "Before every game, a player gives a speech and the manager allows me to feel like a leader, to feel important to the team, and that is always good for a player to feel like you have the confidence of the manager.
"It was me who gave the speech before the Palace game. It was a special one, but I cannot say what I said. It worked, so, yes, I am happy. In terms of age, I'm getting more to the top of the group than to the middle. But I have always said since the beginning of the season that it is a very young, talented team. That as well was one of the reasons that made me sign for the club, because, potentially, this team can be one of the best in Europe."
Eden Hazard crowned a brilliant personal season, during which he won the award for Professional Footballers' Association Player of the Year, by scoring the goal that secured the title for Chelsea against Palace.
Fabregas said: "Eden's had a fantastic season, I just want for him to do it again next year and to be even better.
"He's the main guy. In my mind, he is the guy that makes this team better than it is. Next year he has to prove himself in the Champions League as well because he is capable of that and I am sure he will give many big nights of glory to this club."
Asked specifically if Hazard could be a special player, such as his close friend Lionel Messi, Fabregas said: "He can be one of those, for sure. He can be up there, for sure."
Meanwhile, John Terry insisted that he would not "embarrass" himself and would know when to hang up his boots before anybody else. The Chelsea captain has played every minute of every game of the team's Premier League title success, making a mockery of Rafael Benitez's assessment that the defender could not play two games in a week.
"There will come a point when enough is enough, but I'll know when that is and I'll be the first to say, 'Listen, I can't do this no more,'?" Terry, 34, said. "The last thing I want to do is go out there and get embarrassed every week. It will be for me to say and I'll make sure I'm ahead of everyone else."
During his time as Chelsea's interim manager in the 2012-13 season, Benitez dropped Terry.
The defender said: "I don't need to stand here and prove him wrong. My football's done that for my whole career. That's his opinion and as a player you have to respect that. But it's nice to respond the way I have in the last two years."
