The 35-year-old Portuguese international recently contracted coronavirus but has made a recovery that should not prevent him from taking part in any more games this season, but his current club Juventus are keen to move him on.
The Italian club want his £540,000-a-week wages off the books at the end of this season in order to help manage costs. Juve, like almost every club in the world, has been hit hard by the coronavirus pandemic and while a vaccine appears close to being manufactured, clubs still have to account for the huge amounts of missing gate receipts from the last year, and perhaps for 12 months more.
Ronaldo moved to Juve from Real Madrid two seasons ago and has been a success in Italy, winning two league titles, but the Italian champions have been unable to win a Champions League even with his assistance.
He has also been linked with a move to Paris Saint-Germain, with their transfer head Leonardo acknowledging that the French team are one of the few clubs in the world who can still afford to sign the biggest names.
Ronaldo is still popular with Manchester United fans and he has talked in the past of a return to Old Trafford before his career ends. He would be a popular figure should he rejoin, though it would put in question Edinson Cavani’s role beyond the summer.
Executive vice-chairman Ed Woodward would doubtless want to make the move happen if he could afford it, and with rumours circulating about a potential exit of Paul Pogba this summer, perhaps there is a deal to be struck between the two sides that lets them let one marketable talent go while replacing them at a stroke.
