Floyd Mayweather is still yet to make an announcement on who his opponent will be in September, when the pound for pound number one fighter in the world is set to have his 49th and final bout.
Who Will Be Number 49?
There has been speculation as to who could be the next challenger and the undefeated five-weight world champion most recently suggested two fighters that surprised many in Andre Berto and Karim Mayfield.
Haitian-American boxer Berto is a former two-time welterweight champion and has made a strong return to the ring after suffering back to back defeats in 2012 and 2013. The 31-year-old has since won two in a row, most recently winning in impressive fashion against Josesito Lopez in March where he stopped his opponent in the sixth round.

Karim Mayfield has never fought for a world title and has a record of 19-2-1, with his best win coming against former world title challenger Mauricio Herrera. The 34-year-old, known as 'Hard-Hitta' has a 50% knockout percentage and has campaigned at light welterweight before.
After naming both boxers the 38-year-old Mayweather was asked if he was serious, to which the undefeated fighter stated he was drawing comparisons to rival Manny Pacquiao and his chosen bout with Chris Algieri last year.

De La Hoya bout possible?
The current WBA Super, WBC and WBO welterweight champion has also called out boxing legend Oscar De La Hoya, who is contemplating a return to the ring after being retired for seven years. 42-year-old 'Golden Boy' is reportedly in fantastic shape and has publicly said he will come out of retirement, but only to fight the best. Gennady Golovkin is also touted as a potential opponent.
The rivalry between De La Hoya and Mayweather started from their 2007 fight that the latter won on a close points decision. Since his retirement Oscar has supported every opponent Mayweather has fought as their dislike for one another has not been resolved. Shane Mosley has also put himself in the mix as he publicly tweeted about his desire to go toe to toe with the Grand Rapids man once again.
The Main Candidates?
There are the obvious options for the welterweight champion such as WBC mandatory Amir Khan, WBA regular champ Keith Thurman, IBF champion Kell Brook and Shawn Porter. There is the opportunity of a dream fight for fans against hard hitting Gennady Golovkin but the 1996 Olympic bronze medallist is unlikely to move up to 154 or 160Ibs.
Mayweather has been vocal on 'GGG', recently claiming he would be 'too smart for Golovkin' and admitted he was unimpressed when watching the middleweight champion's last fight.
The undefeated man also shed more light on vacating his world titles. Over the weekend Mayweather played match-maker, suggesting a bout with his protege Errol Spence Jr against either Thurman or Porter would make a great world title fight on his under-card in September.
Every fighter wants the opportunity to crack the 'May-Vinci code' and be number 49. Amir Khan has been the most vocal, with Porter also calling out the champion after his win over Adrien Broner last Saturday.
Keith Thurman has expressed that the only welterweights deserving of a shot are himself and fellow undefeated world champion Kell Brook, who has also said he would be ready for September but has been more vocal about a domestic clash with Amir Khan.
The temptation to fight on for a 50th contest is one which Mayweather has said he is not interested in as he is contracted one more fight with television broadcasters Showtime.
The pound for pound king will have his farewell contest in three months time and whether its against Mayfield, Oscar De La Hoya, Khan or Golovkin its fair to say Mayweather has earned the right to chose who he wants with one of the best resumes in boxing.
The defensive specialist has had a 19-year professional career and has never been hurt or dropped. Unmarked, undamaged and undefeated, the likelihood is that Mayweather will be 49-0 and equal Rocky Marciano's record, whoever the opponent is.
