Blues owner Roman Abramovich is an avid spender of money during both the summer and winter transfer windows but Mourinho is confident that everything is under control at Stamford Bridge.
Mourinho also said that Abramovich would continue to spend within the FFP guidelines even though some of Chelsea’s Premier League rivals may 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."
