Jose Mourinho claims he knew of Sir Alex Ferguson's plans to retire months ago and would have turned down the chance to manage Manchester United in order to return to Chelsea.
The ex-Real Madrid boss is quoted as saying he "would have turned down every job in the world - the Manchester United job, everyone for Chelsea".
Mourinho has signed a four year contract to take charge at Stamford Bridge for a second time.
The manager also says he's told his Chelsea players not to act selfishly otherwise there will be "big trouble".
The final months of his tenure at Real Madrid were blighted by divisions within the dressing room and Mourinho is keen to avoid a repeat.
He said: "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 percent for me, for your fellow players and for the club, we will have a wonderful relationship.
"If you are selfish, if you don't care about the club, don't care about the fans, don't care about the image... we are in big trouble.
"Sometimes you have groups that adapt to this in a very easy way. Sometimes you have groups that this becomes like a doctrine and everything is easy.
"Sometimes you have a couple of guys who are not so keen to accept these kind of rules and this is where you have some problematic relationships."
Mourinho remains close friends with Sir Alex and the pair agree that a regular turnover of managers at a club gives more power to the players.
He added: "What Sir Alex says in relation to English football is doctrine, it's the bible. If he says that with so many years of experience then I think he is correct. Does it relate to this club? I don't know.
"Last season Chelsea won the trophy I don't want to win. I won it with Porto before I won the 2004 Champions League and that is the way it should be done, you win first
the Europa League and after you win the Champions League. I want to go back to always playing in the Champions League and playing in it without risk.
"Two seasons ago Chelsea had risk, if we hadn't won the 2012 Champions League we wouldn't have played in it the following season because we finished sixth.
"This season we also had risk until the last match... so we need to go back to this stability. Stability is important for the development of the young players, for the club, the fan base, for the economic situation that is more and more important with FFP (Financial Fair Play).
"I think the owner and board, they want very, very much this stability."
