Floyd Mayweather could still compete with the best in the world if he returned from his three-year retirement.
That is the view of sparring partner Denis Douglin who recently shared the ring with the pound-for-pound great during 2am training sessions.
Mayweather, 43, has not fought since he extended his unbeaten record to 50 fights with a stoppage win over Conor McGregor in 2017.
He has repeatedly hinted at a comeback – but has admitted it would likely be in an exhibition bout.
But Douglin told Vegas Insider: “I think he could come back.
“As a fighter it’s amazing to see another fighter, especially an African-American fighter, doing so well, making so much money, having fun, milking the game – so why not keep going?
“If you’re safe and you feel protected and you’re smart, I wanna say keep going.
“The last time we sparred was probably three years ago for his exhibition match in Asia and I kind of felt like he was slowing down a little bit. This time he felt sharp, he felt strong, his stamina was great. It was almost like he’s getting better.
“Everything that he’s going through in his life is making him more focused on boxing. I think he could still hang with the top guys. There’s no reason to try because he’s already proven himself, but if he wanted to, he could still do it. With Errol Spence at his best, Floyd can still compete with him 100 per cent.”
Douglin also said he would not be surprised to see Mayweather rematch McGregor – or take on UFC lightweight champion Khabib Nurmagomedov.
“I do think this could happen, I think he’s going to fight UFC guys,” he added. “It’s actually quite interesting because I’m left-handed and McGregor and Khabib are both left-handed, so him choosing to spar me, that might be the reason why.
“That’s something someone said to me the other day and I was like, you know what, that makes sense, so it’s very possible.
“The Conor McGregor fight generated so much money, why not do something like that again or fight another UFC fighter if he’s making millions of dollars?”
