Manchester United boss Jose Mourinho: Man City film showed lack of class

Jose Mourinho has accused Manchester City of lacking class after their behind-the-scenes documentary appeared to poke fun at his Manchester United team.

The eight-part film, "Manchester City: All or Nothing," which premiered in Manchester last week, documented their Premier League title triumph last season.

During it, narrator Ben Kingsley describes City's 2-1 win over United at Old Trafford in December as "Guardiola versus Mourinho once more; possession vs. defence; attacking football vs. park the bus" -- and that did not go down well with Mourinho.

"You can have a fantastic movie while respecting others," the United manager told Sky Sports. "You don't need to be disrespectful to have a fantastic movie.

"You can be a rich club and buy the best players in the world but you cannot buy class and they showed that clearly, that was really obvious."

Mourinho told English newspapers that he should claim "royalties" because he appears in the documentary.

"The second reaction is because I am in the movie I could ask for some royalties," Mourinho joked. "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."

Despite avenging the derby defeat at Old Trafford with a 3-2 win over City at the Etihad Stadium in April, United finished 19 points behind Pep Guardiola's side.

Mourinho takes his team to Brighton on Sunday as he looks to challenge for this season's title, but warned supporters that they may have their work cut out.

"Last season we put ourselves in a difficult position, because to do better we can only finish first," he said.

"When I read sometimes and watch sometimes it looks like we finished sixth or seventh and everybody did better than us. We finished second.

"Liverpool are trying to win the title with their amazing investment. Chelsea have a fantastic squad, Manchester City have a fantastic squad too, Tottenham made an incredible investment by keeping their players, that's the best investment you can make.

"They could be spending £200 million, but if they lose Harry Kane or Christian Eriksen ... the biggest investment was keeping all their best players. Arsenal will be better even though they lost their first match.

"I think it's going to be a very hard season."
