Ronaldo returned to United from Juventus for a second spell at Old Trafford in August 2021, signing on for a two-year deal with the club with which he won eight major trophies from 2003-2009.
In an interview with Piers Morgan for TalkTV, released on Sunday, Ronaldo was asked whether United's higher ups were trying to push him out of the club.
"Yes, not only the coach (Ten Hag), but another two or three guys around the club. I felt betrayed," he said.
"Yes, I feel betrayed, and I feel some people don't want me here, not just this year, but last year too."
Last month, Ten Hag said that Ronaldo had refused to come on as a substitute against Tottenham Hotspur, with the forward walking down the tunnel with a few minutes of the match remaining after being left on the bench.
He was then not included in the squad that faced Chelsea the following Saturday.
The 37-year-old forward, who will captain Portugal at the World Cup in Qatar, said of Ten Hag:
"I don't have respect for him because he doesn't show respect for me. If you don't respect me, I'm never going to have respect for you."
According to Reuters, United did not immediately respond when contacted for comment.
After the Tottenham game, Ten Hag said Ronaldo remained "an important player in the squad".
Ronaldo also said Manchester United failed to support him when he and his partner Georgina Rodriguez's daughter was hospitalised July.
He said the club doubted him, and showed a lack of empathy when he did not arrive on time for pre-season training.
"The fans should know the truth," he said.
"I want the best for the club. This is why I came to Manchester United.
"But you have some things inside that don't help (us) reach the top level as City, Liverpool and even now Arsenal ... a club with this dimension should be top of the tree in my opinion and they are not, unfortunately."
In Ronaldo's first stint at the club, manager Sir Alex Ferguson was at United’s helm, however retired in 2013.
"The progress was zero since Sir Alex left, I saw no evolution in the club. Nothing had changed," Ronaldo said.
"He knows better than anybody that the club is not on the path they deserve to be.
"He knows. Everyone knows. The people who don't see that … it's because they don't want to see, they are blind."
