Manchester United forward Cristiano Ronaldo says the club's owners, the Glazer family, "don't care about the club" on the sporting side.
"Manchester are a marketing club - they get money from the marketing," he said.
"It will be hard for Manchester to be top of the game in the next two or three years."
The 37-year-old Portugal forward, who has only scored one Premier League goal this season, said: "The owners of the club, the Glazers, they don't care about the club, professional sport."
Ronaldo added that he has never met the Glazers, who took over the club in 2005.
