Ramsey took charge in February, following Harry Redknapp’s shock resignation, but was unable to save the Hoops from relegation out of the Premier League.
Despite losing their top-flight status, QPR appointed Ramsey on a permanent basis, but a 1-0 loss against Derby County at the start of November, the club’s fourth successive defeat away from home, was the final straw.
And Onuoha is adamant that he will never become a manager once his playing days are over, explaining that any satisfaction from the role is always outweighed by pressure and stress.
He was reported by Get West London as saying: “Personally, I’ve never wanted to be a manager.
“I enjoy playing, but then to come in for longer hours with twice as much stress and trying to control five times as many people, it’s not for me. You can have that on tape for as long as you want.
“I think I’ve had 10 managers in 11 years, so it’s something I’m quite used to.
“When I was younger I thought I might stay in football, but when I retire I might stick to watching it on TV.”
Onuoha also paid tribute to former manager Ramsey, adding: “I do appreciate the fact that he basically played me for his whole tenure here and I am the captain now so I can’t thank him enough for that.”
