The 36-year-old hung up his boots last month after a career spanning 19 years and more than 600 appearances.
And Neville said in an interview with MUTV: "It was a struggle towards the end for me. I was ready for it, when people finish their career they miss it. I feel content and happy, watching the games and enjoying it."
His efforts for United are likely to be remembered in a testimonial match at the end of the season, with an announcement due within the next couple of weeks. But the former United captain does not miss the strict regime he had to follow to continue a career at the top level of European football for so long.
He explained: "Hotel, rest, match, eat, sleep. That was the pattern, you are institutionalised into being like that. You have a privileged lifestyle but have to be professional."
Despite not missing playing for United, Neville is still a huge fan and was shown in amongst the fans during the 2-1 defeat at Chelsea. He added: "I just wanted to go and watch a few games normally, we decided to queue up outside. I wanted the real atmosphere and really enjoyed it. It was a different experience."
