Super-agent Mino Raiola has stirred it up with neighbours Manchester United and City, revealing his long-term feuds with Sir Alex Ferguson andPep Guardiola.

The 53-year-old claimed it would not bother him if he never moved a client to either club again, which could be good news for Chelsea.

One of Raiola’s most famous clients is young star Erling Haaland who is reportedly on the Blues’ radar for a summer transfer.

Haaland is wanted by Manchester United as well and the Norweigan striker is also a key target for Guardiola’s team as City prepare for life without Sergio Aguero next season.

He told the Athletic: “With Mr. Ferguson or [Pep] Guardiola, I have this problem — and I think that it is changing now — that (they believe) we should submit to them because ‘otherwise, tomorrow, you don’t do a player with Manchester United’.

““I don’t give a f**k if I never do another player with Man Utd. I’m not in their hands. I’m independent. We have only one party that we take care of: our players. And as long as our players like us, you do what you have to do.”

“Guardiola? I’ve closed the book a long time ago. Everybody knows what I think of him personally; he can say what he thinks for me personally.”

Raiola also represents Italian goalkeeper Gianluigi Donnarumma, a player reportedly on the radar of both Chelsea and Manchester United. Any rift between the powers at Old Trafford and Raiola could play into Chelsea’s hands were they to make a move for the 22-year-old.
