Mike Tyson calls Floyd Mayweather 'delusional' over outrageous claim

has savagely criticised following the latter's bold assertion that he was better than great Muhammad Ali.

Ali - who is regarded as one of the biggest names in the history of boxing - transcended the sport of boxing. The icon is the only fighter to win the lineal heavyweight championship on three occasions and his legacy includes epic showdowns like the 'Rumble in the Jungle' with George Foreman.

Despite retiring in 2017, Mayweather couldn't stay away from the ring and has been involved in several exhibition fights over the last few years.

Meanwhile, Tyson - another fighter who is regarded as one of the greatest heavyweights of all time - seized the heavyweight championship in a ferocious beatdown of Trevor Berbick back in 1986 at just 20 years old. His ended his career in 2005 after a loss to Kevin McBride.

However, the now 58-year-old stunned the boxing last year after announcing his return to the ring, taking on YouTuber-turned-boxer . But alas, Tyson was unable to roll back the years on fight night. Despite failing to secure a knockout, the 'Problem Child' .
