Sheffield United are just two points behind Chelsea, who currently occupy fourth position in the Premier League.
Tottenham are four points behind Chelsea, while Everton’s dramatic improvement under Carlo Ancelotti has them just five points off the pace.
Manchester United and Wolves trail by six, while Arsenal, who have registered just one win in the Premier League under Mikel Arteta, are 10 points off the final Champions League place.
But when listing the teams vying for fourth place, Mourinho gave no mention of his former club.
“Wolves and Sheffield United are fighting for the top four, [the managers] they can say no, and I understand if they say no but the reality is that they are. Not just because of the position that they are in the table, but because of the power and quality,’ Mourinho told Sky Sports.
“They arrive in this situation where in the eyes of everybody they should be more than happy, they are not more than happy.
“Wolves bought an important player [Daniel Podence for £16.6m] to try to improve their situation.
“Sheffield bought an important player [Sander Berge for £22m], they beat their record in the market to try to improve their team.
“So it’s not just about Tottenham, Arsenal, Chelsea and Everton. It’s not just about us. ‘It’s also about these two clubs who I have to say [are] fantastic.”
