Manchester United and Ronaldo, 37, parted ways in the middle of the season following the player’s explosive interview with SunSport columnist and TalkTV host Piers Morgan.
The five-time Ballon d’Or winner accused Manchester United of betrayal and blasted the club’s lack of investment in infrastructure.
Current United figures such as manager Erik ten Hag were targeted, with Ronaldo admitting he has no respect for the Dutchman.
Former teammate Gary Neville and Wayne Rooney were also chastised for their comments.
Ronaldo got his wish to leave Manchester United, albeit a few months late, after slamming the club. And non-league AFC Crewe have seized the opportunity to try to sign the legendary forward on a club-record £35-a-week contract – a significant reduction from his £500,000-a-week contract at United.
The 14th-tier Crewe and District League Premier Division club held a whip-round to fund the free agent’s transfer.
“We can confirm that the club has made an official approach to sign free agent Cristiano Ronaldo on a one-year contract,” they tweeted.
“If Cristiano accepts the offer, he will be AFC Crewe’s highest-paid player, earning £35 per week.”
Ronaldo’s future will most likely be decided after the World Cup, where he will captain Portugal.
The Euro 2016 champions are in Group H with Ghana, Uruguay, and South Korea.
Portugal plays Ghana in their first group match on Thursday.
