Floyd Mayweather obviously loves winning, going by his 48-0 boxing record, but former rival Ricky Hatton has explained to what lengths the Money Man will go to avoid losing at anything.
The Brit shares a story in his recent book about Mayweather going to extreme lengths to win an air race to Las Vegas when they were travelling separately to promote their 2007 fight.
Hatton reveals that Mayweather was not happy that his private jet was trailing the Brit's plane and ordered his pilot to perform a dangerous overtaking manoeuvre in mid-air.
"A few minutes into the journey, we're chatting away, having a drink when the pilot gestures to me to come forward. 'Hey Ricky, listen to this idiot,'" Hatton writes.
"He turns on the speaker and over the radio I hear Floyd arguing with the pilot of his plane behind: 'I'm not letting that motherf***er get there before me, f***ing overtake them!"
