Jose Mourinho will warn all of his Chelsea squad to do it his way next season or leave Stamford Bridge. Chelsea secured back-to-back Premier League titles under Mourinho's last regime in addition to winning the FA Cup and also the League Cup twice.
Former Manchester United manager Sir Alex Ferguson, who is very close to Mourinho, often lamented the rise of player power within the modern game and the Portuguese sees no issue with maintaining the image of the club during his second tenure after agreeing a four-year deal to return following his departure from Real Madrid.
"What Sir Alex says in relation to football and management is doctrine, it is the bible, so if he says that (about player power) with so many years of experience, I think he is correct," said the new Chelsea boss.
Mourinho, who won the UEFA Champions League for a third time when manager at Inter Milan after leaving England, continued: "There is something I say whenever I go to a new club and I am going to say it again when I meet the players on July 8 - and some of the boys will have heard it before from me.
"It is a sentence I always say on the first day: 'If you are a top professional, if you are not a selfish person, if you put the club in front of yourself and if you are here to work 100 per cent for me, for your fellow players and for the club, then we will have a wonderful relationship.
"If you are selfish, if you think about yourself and you don't care about the club, don't care about the image, if you don't care about the fans then we are in big trouble, so it depends on you if the relationship is fantastic or if it is not fantastic. Sometimes you have groups that adapt to this in a very easy way; sometimes you have groups that it becomes like a doctrine, and everything is easy.
"Sometimes you have a couple of guys that are not too keen to accept these kind of rules and this is where you have some problematic relationships, and the club in that moment either supports the problematic player or the manager. If the clubs supports the manager the two little guys - gone, easy."
Second time lucky
Despite history proving second comings do not always turn out for the best, the man who once famously described himself as a 'Special One' sees no reason why he cannot break the mould.
"These are like urban myths, football dogmas," said Mourinho, who earlier this week moved to bring in 22-year-old Germany forward Andre Schurrle from Bayer Leverkusen as the club looks towards the future.
"The club knows me, I know the club. I don't think this should work negatively, I think this should be a plus not a minus. I come here now and it's completely different than if I arrived in a club for the first time. It should be a plus, something that helps us to do it well.
"I am feeling I am coming back - it is my dugout, where I never lost a match, my stadium, my dressing room, it is my office at Cobham with the same table. Emotionally you get it, but from a pure professional point of view it is not different to arriving at a new club, it is the same ambitions. I don't want people to think that this is comfortable for me - it is more difficult, and that is what I want."
