The Portuguese manager claims that the Blues have to adhere to Financial Fair Play rules more stringently than the likes of Manchester United, Barcelona and Real Madrid, citing the recent sales of David Luiz, Romelu Lukaku and Juan Mata as evidence.
Chelsea spent approximately £100,000 net from their business this summer - bringing in Cesc Fabregas, Diego Costa, Filipe Luis, Didier Drogba and Loic Remy - and Mourinho says that this is the reality of managing a club with smaller incomes.

"So Real Madrid, Barcelona, Bayern, Manchester [United] – all these huge teams, I think they have an advantage.
"But at Chelsea we are so happy with the way we are doing things, with this great balance between the income and the money we can spend. We are so happy with that profile of club we are, we don't want to change."
The Blues have shot to the top of the Premier League with three wins from three but Mourinho believes that the club are unlikely to break the British transfer record - something that they have done twice in the past - again.
When asked if the Blues could eclipse the £59.7 million that United spent on Angel Di Maria, Mourinho stated: "Chelsea not, for sure, because Chelsea is working in relation to the Financial Fair Play.
"We are making money to be able to spend money. In every transfer window Chelsea is losing players, is selling players. In the winter one we sold Mata; in the summer one we sold David Luiz and Lukaku.
"So Chelsea in this moment is not a spender – Chelsea in this moment is making more money in transfers than the money we spend."
