Tyson Fury has warned Cristiano Ronaldo that time waits for no man after insisting the Portugal star is 'on the slide'.
The British boxing star, who is also a fan of Manchester United, has compared Ronaldo to Wladimir Klitschko at the end of the Ukrainian's boxing career.
Ronaldo has been dropped to the bench in recent times for both the Red Devils - before his tumultuous exit - and most recently against Switzerland in the last-16 of the World Cup for his country.
Fury told talkSport that he thought beating Klitschko in 2015 was the 'Everest' but admitted that other factors such as age come into a sportsman's career.
