City’s two-year expulsion from UEFA competitions was lifted by the Court of Arbitration for Sport on Monday, meaning they are free to compete in next season’s Champions League.
Mourinho’s anger is not directed at City, more at the powers who govern the rules, and he wants an end to the FFP system despite agreeing with it in principle.
Tanguy Ndombele’s fitness issues continue after the France midfielder picked up another injury in training.
Mourinho, who earlier this season said the club record signing was “always injured”, says the knee problem is not serious, but enough for him to be a doubt at St James’ Park.
He said: “He was training with the group of players that didn’t play against Arsenal (2-1 win on Sunday) and then in one action he felt something behind his knee.
“Nothing major, nothing really big but enough for him to leave the training session and to be observed before the training session.”
