The Blues boss believes that City's spending has put the club under the biggest pressure to succeed, while he hopes the Financial Fair Play rules are respectedChelsea manager Jose Mourinho claims Manchester City's summer spending means they must avoid further purchases in January and believes Manuel Pellegrini is under the most pressure to win the title.
Last season's runners-up spent nearly £100 million on five new players despite the threat of the new Financial Fair Play regulations, and the Portuguese feels such strengthening marks them as the biggest threat in the Premier League.

"I mean the quality and profile of the players, the experience of the players, and the average age - they don't have old players or very young players.
"You see all of them, players with big maturity and experience: (Sergio) Aguero, (Edin) Dzeko, (Alvaro) Negredo, even (Stevan) Jovetic.
"These are their four strikers, but go through the positions and you see (Yaya) Toure, Fernandinho… nobody more than 30, nobody below 23. The squad is amazing.
"They have solutions and solutions and solutions. If you ask me which team has more ammunition, I have to be honest.
"I have to apologise to the other four in case they're not happy with what I say but City are the team with more ammunition. They are a team able to make a run of victories."
Chelsea, in comparison, spent around £65 million in the summer, and Mourinho feels the FFP rules have made an impact in the transfer market already, but is wary of the willingness of teams like City and the seriousness of the regulations.
"I hope Financial Fair Play is for everybody and not just for some because we care about Financial Fair Play," he continued.
"We look at it, we respect it, we prepare ourselves for the future based on Financial Fair Play coming into action. I hope it applies to everybody.
"We are worried about the spending. We have a board, we have an economic department working hand in hand with the sports department, and we want to respect it.
"We know our owner is a special person in the economic world and has incredible potential to show his passion for this club and for football, but Financial Fair Play has an objective to control the differences between owners and clubs.
"January is a period where we will see whether it is or is not (being implemented)."
