Despite Floyd Mayweather insisting that he is retired for good, former world champion Amir Khan isn't afraid to potentially call out Mayweather to a boxing match.
Khan has been out of action for well over a year, but he has been training for a potential return fight in the coming fights. On Twitter, Khan spoke about Mayweather and hinted that he could potentially beat Mayweather in a not so subtle manner.
Khan referenced his fight against Canelo Alvarez, Khan's last fight before being out of action due to surgery. Khan was knocked out by Alvarez in the sixth round in May 2016 and Khan was only winning on just one of the three judges' scorecards. Alvarez previously lost to Mayweather in 2013. Khan has been linked to a possible grudge match against longtime British rival Kell Brook as Khan's return fight.
On the flipside, Mayweather came out of retirement to fight UFC lightweight champion Conor McGregor on August 26. Mayweather won that fight to improve to 50-0. Mayweather has repeatedly said his fight against McGregor would be his last boxing match.
