Instead of fighting Manny Pacquiao in 2015, as rumors say, Floyd Mayweather Jr. expressed that he might retire next year.

The undefeated boxing champ will face Marcos Maidana on Saturday but his next two contenders are still unknown.

"I can't say who the next two opponents will be, but they will be exciting fights. My next fight is in May and then September. A year from now will be my last fight," he said in a Sky Sports report.

He, however, cleared that his focus as of the moment is really on the Argentine boxer whom he will fight in a battle for his WBA and WBC welterweight and light-middleweight titles. Mayweather also highlighted that he wants to stay healthy as possible as the fight nears.

"As you get older, you get wiser, smarter. You no longer grow physically but you do mentally. When I was younger I would go to the gym, every day, even as a professional. As you get older you have to let the body rest, let the body heal and rejuvenate so you can come back a lot stronger. Over the last few years I have let my body rest a lot more, eat a lot better although I cheat a little at Fatburger," he added.

The American fighter who remains undefeated at 46-0 also claimed that he has improved his speed with constant training months before the fight.

"I am capable of changing. I'm faster this camp, a lot stronger, feel a lot better. We will have to see how the fight plays out. I am sure he is in good condition and we'll see what he brings. I think I am faster because I am throwing more combinations this camp. The sparring partners have said I am a lot better. We have used some of the same guys and they say I am a lot stronger and faster this camp," he added in an interview with Sky Sports.

Though Mayweather expressed his plan to retire next year, fans waiting for the Pacquiao-Mayweather clash should not lose hope as the American fighter, according to The Guardian, "still wants Pacquiao."

The report said that as both fighters head towards retirement, Mayweather sees Pacquiao as his "endgame" which will seal his record in boxing. 

Top Rank CEO Bob Arum, in a Telegraph report, said that Mayweather cannot continue running from a match up with Pacquiao as network restrictions between HBO and Showtime have already been ironed out.

"That was the biggest impediment in my mind. That is no longer an impediment. We are not an impediment. There's no drug testing problem, nothing. We are ready to do the fight. There is only now one impediment and he's been the major impediment to this fight and that's Floyd Mayweather," Arum added.
