City were banned from the Champions League for two years on Friday, although they have made their intention to appeal the decision clear.
If the ban was to be upheld on appeal, the fifth placed Premier League side this season would be given a Champions League spot instead of City – assuming City will finish in the top four.
Mourinho told Sky Sports: “Wolves and Sheffield United are fighting for the top four. [The managers] can say no, I understand if they say no, but the reality is that they are.
On Sunday, after Mourinho saw his Spurs side snatch a late win at Aston Villa to lift them into fifth, the former United boss has been asked about how City’s ban affects the race for a Champions League place.
Mourinho again missed United out when speaking to BBC Sport but did included them in his contenders to qualify when he sat down to give his post-match press conference.
“There is a big fight,” he said.
“You could see yesterday Liverpool, first against the last, you could see today Villa fighting to stay in the division and us fighting for top position, how difficult is is. This is the Premier League.
“So when we speak about the fifth spot, I think for sure Wolves, Sheffield United, Man United, Arsenal, Everton, everyone looks to the table and week after week they say we can do it and they can. It’s going to be very hard.”
