Speculation regarding Ronaldo's desire to leave Old Trafford in this window has not relented ever since reports emerged at the weekend that he has told the English giants he wants out.
The 37-year-old was supposed to attend his first day of pre-season under new Red Devils boss Erik ten Hag on Monday, but missed it due to "family reasons", and reportedly did not attend training on Tuesday for the same reason.
This has cast further doubt on his stay in Manchester, although United are said to be adamant about keeping him for the final year of his contract.
With Ronaldo believed to be eyeing UEFA Champions League football next season, it has now been claimed the five-time Ballon d'Or winner is willing to take a considerable pay cut in order to leave the Red Devils for a club that competes for top honours, per The Independent.
With the marksman on a reported £500 000 (R9.9 million) a week at Old Trafford, he is now understood to be willing to be paid less because of a genuine lack of interest in his services.
There are suggestions that Chelsea are one of a few interested parties in the forward, while his agent Jorge Mendes has also reportedly offered him to FC Barcelona.
The Blues' new co-owner Todd Boehly is said to have met with Ronaldo's super-agent Jorge Mendes, but no official offer has been put on the table by the American businessman, while a meeting between the representative and Barca president Joan Laporta is also believed to have taken place.
Paris Saint-Germain and Bayern Munich, who could soon lose star striker Robert Lewandowski, are also said to be among the player's preferred options for his next destination.
