Cantona claims Ronaldo left the biggest club in the world when he joined Real Madrid this summer.
The Frenchman believes Ronaldo only left United because of the money.
“I can’t understand why he [Ronaldo] would want to leave United,” said Cantona.
“For me the biggest club in the world is United. When you are at United, if you don’t have a problem with the club, if they give you the contract and if they really want you to play, then you can’t have any problems. I don’t understand why he’d want to leave.
“All the owners of clubs now are businessmen.
“I’m not sure if football was like this 20 years ago. I’m not sure these people would buy United or Chelsea or Liverpool then.
“When we see these kind of businessmen as owners of the clubs I’m not surprised that they don’t care about working-class fans.”
