Gary Neville has said Manchester United "know they have to terminate" Cristiano Ronaldo's contract.
In an interview with TalkTV, the Portugal forward said he had no respect for manager Erik ten Tag and felt "betrayed" by the club.
Ronaldo also criticised on the club's owners and his former United team-mates Neville and Wayne Rooney.
Supporters have been critical of the striker, with some believing he is ruining his legacy at Old Trafford.
He wouldn't have done this interview if he wanted a way back. He knew it would bring the headlines it has and be the end of his Manchester United career," Neville told Sky Sports.
"I'm wondering what Manchester United are doing because the reality of it is they know they have to terminate Cristiano's contract or they basically open up a precedent so any player can criticise them in the future.
"I agree with some of the things Cristiano has said, and many Manchester United fans will agree with many things Cristiano has said, but the reality is if you're an employee within a business and say those things your employment has to terminate, and Manchester United have to do that in the next few days."
Neville argued the club are also partially responsible for the way the relationship with Ronaldo has deteriorated.
