Last week, Floyd Mayweather called out legend Muhammad Ali, saying that, when it comes to who is the greatest, it’s Mayweather.
On Monday, Ali appeared to fire back on Twitter, although he did not mention Mayweather by name.
Ali twittered “Don’t you forget, I am the greatest”.
Mayweather had told ESPN that no one could brainwash him to make him believe that Muhammad Ali was better than him.
Mayweather will fight Manny Pacquiao at about 3pm Sunday, and you can watch it live on Sky Pacific’s Pay Per View channel for $40 for residential customers and $300 for commercial customers.
