Floyd 'Money' Mayweather announced the end of his career earlier this month after a dominating points victory over Andre Berto to take his perfect record to 49-0.
But whilst the five-weight world champion appears content in his decision to hang the gloves up, there are many people who still believe that 'Money' will return for one last fight.
A 50th fight?
It would make perfect sense for one more fight, the chance to overtake the great Rocky Marciano's undefeated record and the opportunity to win half a century of fights. The number 50 is perfect and although the 38 year old's career has never endured a single loss, there is still a lingering feeling to end a career on 49 fights.

The options are there for the 1996 Olympian and with his recent online activity, Mayweather appeared to take aim at one of his rivals.
Mayweather's dig at Khan
On Mayweather's own website, an article was recently posted headlined:
'AMIR KHAN TRIES TO STUNT, GETS BLOWN OUT THE WATER BY MONEY MAYWEATHER'.
The main content of the article was about the watch collections of both fighters with Amir recently posting a picture of six of his watches on instagram believed to have a total cost of more than $385 thousand.
Coincidently Mayweather also posted a recent picture showing 24 of his watches with Floyd's total cost surpassing more than $7.7 million.
The article itself may seem irrelevant but the undefeated fighter shared the story on his Facebook page so it would get more publicity. At the end of the article the writer taunted Khan about the difference in expense between both fighter's watches.
"Many fans in the world of boxing predict Mayweather vs Khan would be a close match up. Thus far, Floyd is scored 10-8 in this round. Floyd moving like a boss!"
'King' v 'Money'
Is it a final dig though? Or could this discussion of who's the flashiest be a small mind game set by Mayweather to promote a massive build up to a 50th fight against 'King' Khan?
The Bolton man put his career on hold for two years in the belief that he would land a fight with the pound for pound number one. The 28-year-old turned down the chance to fight for a world title in December 2013 and has also remained fairly inactive having only fought twice in 2014 and once this year.
The former two-time world champion is now looking for a mega fight with Manny Pacquiao next year.
A win against Pacman would definitely put Khan up for contention for the 50th bout, with many fans believing that the former Olympian does not deserve the Mayweather fight as he is yet to fight an elite 147Ib opponent.
In the world of boxing, comebacks always occur and with Floyd Mayweather's recent masterclass against Berto it would be a shame for the Grand Rapids fighter to call it a day when he is still at the top of his game and only one fight away from breaking the record.
Leaving at the top is extremely rare in boxing but it is what the 38-year-old has managed to achieve with his undefeated resume intact. The lure of one more fight could be tempting for 'Money', it all depends though on how much he misses boxing and how much the boxing world misses him.
