The 36-year-old has been linked with a sensational return to the Theatre of Dreams, with Juventus open to offers for the Portugal captain.
The Old Lady scrapped a Champions League finish last term, which saw Andrea Pirlo sacked and replaced by former boss Massimiliano Allegri.
Ronaldo is in the twilight years of his career and doesn’t want to wait for Juventus to rebuild in order to win major silverware again, which has sent him linked with a return to United 12 years after his departure.
However, Ferdinand believes United would be wrong to make a move for their former talisman.
‘I don’t think Ronaldo will happen,’ Ferdinand told the Sun.
‘That chapter has been written and it’s closed so I don’t think there’s any chance of that happening.’
Ole Gunnar Solskjaer’s priority this summer is signing Dortmund winger Jadon Sancho and the Norwegian is prepared to spend most of his budget on signing the playmaker.
Kieran Trippier is another target, with United hopeful of landing the England full-back for around £12m.
However, Solskjaer would ideally like to sign a centre-back too and the club may need to raise significant funds if they’re to finance a move for the likes of Real Madrid star Raphael Varane.
While the Frenchman is Solskjaer’s first choice, Ferdinand believes this summer’s European Championships could help the club discover other targets.
‘What’s good about the Euros is there will be a good few centre-backs on show there,’ said Ferdinand.
‘It’s also about who is available. I went to the World Cup and got bought off the back of a good season but also playing at a major tournament.
‘This is a great opportunity for someone else to put themselves in the shop window and be purchased by a big club.
‘Manchester United are in the market for a centre-back so what an opportunity for someone.’
