The 36-year-old has been released from the national squad ahead the World Cup qualifier against Azerbaijan on September 7 due to suspension and will head to Manchester to complete a five-day quarantine before joining up with his new team mates.
At the age of 36, many people have questioned whether Ronaldo still has what it takes to shine in England, but Parlour has no worries about his physical condition.
‘He’s got 111 goals for his country, it’s amazing isn’t it,’ he told TalkSPORT.
‘He’s been unbelievable, it amazes me when people say he won’t be able to do it in the Premier League. Of course he will. He’s done it in every league and if you look at the fitness of the guy, he’s not a normal 36-year-old is he? You’d have him down as 31, 32 maybe maximum.
‘He’ll be ready to go, what he’ll do so well is he won’t use his energy up for the sake of it, he’ll do it at the right time. When you get older you learn when you need to do a bit of running and it’s all about that movement of a striker, you just get half a yard, you get across your man. I think he’ll have no problem in the Premier League.’
The Portuguese attacker could make his sensational United return against Newcastle at Old Trafford on September 11, in what could be a momentous occasion for the club.
In his first interview since the move, Ronaldo could not hide his excitement about returning to England.
‘I was there at 18 years old and of course I’m so happy to be back home after 12 years. So I’m really glad and looking forward to start my first game,’ he said.
‘I think it’s the best decision that I have made. It’s right on point in my opinion.
‘I moved from Juve now to Manchester, it’s a new chapter, I’m so happy and glad, and I want to carry on again, to make history, to try to help Manchester achieve great results, to win trophies and number one of them, to win great things.’
