In a thinly-veiled swipe at Manchester City - owned by Sheikh Mansour's Abu Dhabi United Group and Mourinho's favourites for the Premier League title following another summer of lavish spending - the self-proclaimed 'Special One' insisted the Blues are complying with FFP regulations while others are not.
"If the Financial Fair Play comes into place, it should come for everybody, not for some," Mourinho told Sky Sports News at the Football Writers' Association dinner on Sunday.
"Chelsea at this moment is working very, very well, thinking that the Financial Fair Play is going to be in place and we have to obey certain rules.
"(But) our owner (Abramovich) is still the same owner and his passion for football is still the same. If we are free to spend our owner is more than happy to be free to spend.
"Our owner is respecting the new rules that we are waiting for and hopefully, for the good of football, it's for everybody, not just for some."
Mourinho has spoken of a different project at Chelsea, after Abramovich's multi-million pound injection helped him lead the Blues to their first championship in 50 years during his first spell at the club.
Now Mourinho's task is different as Chelsea go along with the FFP rules put into place to ensure clubs can be self-sufficient and not reliant on wealthy individuals who, potentially, could walk away and take their money with them.
He added: "We think about ourselves, we work in a balanced way. We are building a team.
"We will build the team without the massive investment in the short period of time like some clubs are still doing."
