Everyone is talking about Manchester City’s new Amazon Prime documentary, All or Nothing, right now.

The eight-part behind-the-scenes documentary has given an unprecedented insight into how Premier League champions run their club - from training to post-match celebrations in the changing room.

And it’s caused a stir as well with a certain Jose Mourinho.

In episode two, the narrator Sir Ben Kingsley has some rather negative things to say about Man City’s rivals Manchester United.

Ahead of the first meeting between the two sides in the documentary, Kingsley says: "It is Guardiola versus Mourinho once more; possession versus defence; attacking football versus ‘park-the-bus’."

And it seems Mourinho isn’t too happy about it at all.

“I think you can have a fantastic movie respecting the others,” Mourinho said.

“You don't need to be disrespectful to have a fantastic movie. But you can be a rich club + buy the best players in the world, but you cannot buy class. And they showed that clearly.

“Because I am in the Man City documentary, I could ask for some royalties. 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, I give up about the royalties."

Woof.

And City have responded.

According to the Sunday Times, the champions have refused to apologise.

The report states: “City have claimed they had no editorial input or control over Amazon’s film-making, apart from sensitive commercial or personal information that they reserved the right to remove. The depth to which Mourinho and United are mocked has clearly angered the manager and soured relations.”

The rivalry between Guardiola and Mourinho and City and United has just become even more sour…
