Blues manager Jose Mourinho is convinced that owner Roman Abramovich will bankroll another spending spree if required, and he couldn't resist a dig in City's direction.
According to Nick Lustig of the Daily Star, the Portuguese noted:
If the Financial Fair Play comes into place, it should come for everybody, not for some.
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.
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.
It was a clear reference to the ongoing project in the blue half of Manchester, the master of mind games at it again.
Mourinho himself has already been active in this transfer window. Former player Nemanja Matic has returned to Stamford Bridge via an excursion to Benfica.
At £21 million the midfielder didn't come cheap and his signature follows that of Samuel Eto'o, Willian, Andre Schurrle and Marco van Ginkel, who were all secured in the summer.
However, Chelsea won't be falling foul of the FFP rules just yet with rumours of an £80 million move to Paris Saint-Germain for Eden Hazard (per Metro), and a £40 million deal to take Juan Mata to Manchester United (per Daily Mirror).
Mourinho's side have won their last six games in all competitions and are sitting pretty on the coat-tails of City and table toppers Arsenal in the chase for the Premier League title.
The beginning of February sees Chelsea take on Manuel Pellegrini's swashbuckling side at the Etihad Stadium in a game that will tell us much about the credentials of either side. City are far and away the top scorers in the division, with Chelsea second only to Arsenal for goals conceded (per PremierLeague.com).
The unstoppable force meets the immovable object.
Come kick-off time, Mourinho may well have spent even more of Abramovich's fortune.
Such rebuttals won't deter the Special One, who will work hard until the end of the window to bring reinforcements to a side he wants crowned Premier League champions once more.
