Premier League champions Manchester City are a “rich club” but “cannot buy class”, says Manchester United manager Jose Mourinho.
Mourinho was responding to a question about City’s £10m Amazon Prime documentary All Or Nothing, which was released earlier this week.
Pep Guardiola’s side won last season’s title with a record haul of 100 points.
Mourinho said: “I think you can have a fantastic movie, respecting others. You don’t need to be disrespectful.”
A film crew was given behind-the-scenes access – including to the dressing room – for an eight-part documentary about City.
“I haven’t seen it but I know a few things about the movie. My reaction is if you are a rich club you can buy top players, you cannot buy class. That is my first reaction.
“The second reaction is because I am in the movie, I could ask for some royalties.”
City could have won the title by beating rivals United at Etihad Stadium on 7 April and were 2-0 ahead at half-time, but their opponents turned the game around to win 3-2.
The hosts had printed souvenir T-shirts in the hope they would clinch the title that day, but the celebrations were delayed by two weeks.
“You know, a movie without me doesn’t sell much. I needed to be there.
“But if they send me one of the shirts they had in the tunnel when we played there, the shirts that were saying: ‘We did it on derby day.’
“If they send me one of these shirts, I give up about the royalties.”
