Floyd "Money" Mayweather Jr. recently defeated Marcos Maidana to improve his professional record to a perfect 47-0.

Mayweather may be 37 years old, but he's still the champion, and everyone wants a piece of him. Mayweather will take everything into consideration including pay, size, location and date.

Here are five boxers Mayweather should consider facing next.

1. Manny Pacquiao

This is the fight that everyone has wanted to see for years. Mayweather against Pacquiao would draw in the high television ratings, sell out crows and certainly the biggest betting odds. Boxing fans have wanted this fight for years but Mayweather's refusal to offer more than 13 percent of a fight that would pay over $300 million have helped the process. Pacquiao would love nothing more than to get in the ring with Mayweather one-on-one, but the Mayweather camp seems to want nothing to do with facing Pacquiao. Facing Pacquiao would certainly do a lot for Mayweather's legacy.

2. Keith Thurman

Thurman is the most underrated boxer today. The young 25-year-old Thurman is a perfect 23-0 in his young career, and he packs one of the hardest punches today. "One Time" would be a terrific match-up for Mayweather; a classic traditional fight of speed against power. But, on the other hand, Would Mayweather want to fight Thurman? Many boxers are showing fears, in the Welterweight division, to fight Thurman because of his knockout power.

3. Timothy Bradley

Timothy Bradley is currently ranked No. 3 in the Welterweight division, behind Mayweather and Pacquiao. If Mayweather won't fight Pacquiao, then Bradley should be next on his list. Pacquiao already showed guts by fighting Timothy "Desert Storm" Bradley twice, winning the first and losing the second one. Bradley's loss to Pacquiao is the only defeat on his resumé, so he deserves a chance to fight Mayweather. Both Mayweather and Bradley are small, fast fighters who could give fans a good fight.

4. Peter Quillin

Unlikely, but it would make sense for these two to face off. Mayweather has already defeated most of his Welterweight division opponents, except Thurman and Pacquiao. Why not gain a few pounds and face someone in the Middleweight division? Mayweather has already defeated Miguel Cotto, who is the No. 1 ranked boxer in the division. Peter Quillin has called out Mayweather before, and he is only eight pounds heavier. The Cuban boxer is also undefeated in his career, which would set up a good fight.

5. Marcos Maidana

Unfortunately, this is a possibility, again. Maidana can't beat Mayweather, and Mayweather knows it. If Mayweather wants to enhance his legacy, he would choose to fight one of the first four boxers listed above. On the hand, if the aging Mayweather just wants an easy pay day and a simple victory, then he just may choose to fight Marcos Maidana again in his next fight or in the future.

Other notable boxers Mayweather may face include: Miguel Cotto, Canelo Alvarez, Carlos Molina, Amir Khan and Juan Márquez.
