Once it's on the Internet...
Manny Pacquiao has taken a cheeky dig at Floyd Mayweather on Twitter in a now-deleted tweet.
Mayweather posted yesterday, in part of the build up to his big fight with Conor McGregor, that "talking doesn't win fights".
Pacquiao fought Mayweather back in 2015, a fight Mayweather won by unanimous decision after Pacquiao landed just 9 per cent of jabs and 19 per cent of total punches, according to fight statistics.
Pacquiao might still be dwelling on that one, cheekily reminding Mayweather that, although taking doesn't win fights, "running does".
He's since deleted the tweet.
Some boxing fans have noted it's the hardest hit Pacquiao ever landed on Mayweather.
