The Chelsea coach has hit back at the club's claims over the Blues' spending, and says City has only bought players for the next 'three or four years.'
Jose Mourinho believes Manchester City has built a team that is focused on short-term success rather than long-term financial stability after hitting back at Manuel Pellegrini's claims over Chelsea's transfer dealings.
The Stamford Bridge manager was responding to comments from his City counterpart in which the Chilean intimated that Mourinho's "little horses" are still "very rich."
The Chelsea coach insists his side has spent wisely in the January transfer window in order to comply with UEFA's Financial Fair Play ruling, whereas City has spent in spite of the regulations.
"(City) have a team for now, not for 10 years, but for three or four — so experience, potential, power — and not worried about Financial Fair Play because in the summer they spent," Mourinho told reporters.
"Academically [Pellegrini] is an engineer and he does not need a calculator to work it out. [Juan] Mata was sold for 37 million pounds, [Kevin] De Bruyne 18 million pounds.
"That is 55 million pounds. We brought in (Nemanja) Matic for 21 million pounds and (Mohamed) Salah for 11 million pounds — that is 32 million pounds. So 55 million pounds minus 32 million pounds is 23 million pounds. So for Chelsea in this window it is 23 million pounds — he does not need a calculator for this."
Mourinho's men lead the Premier League by a point after Arsenal lost 5-1 at Liverpool, while City was held 0-0 at Carrow Road by Norwich.
