'Money' emerged as winner but McGregor has claimed he would come out on top in a rematch.
Denis Douglin is currently sparring with the undefeated boxer and he thinks he was chosen due to being a southpaw, the same as McGregor.
The 32-year-old Vegas Insider: "[A fight against McGregor or Khabib?]

"I do think this could happen, I think he's going to fight UFC guys.
"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 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?"

Mayweather retired from professional competition after defeating the Irishman and he holds a 50-0 record.
He hasn't slowed down in retirement however and Douglin added he gets called in to train during the early hours of the morning.
"He [Mayweather] called me up around 1am," he continued. "I know he likes to train at night. So I got up and told my mother that Mayweather wanted to spar.
"We got to the gym before him, I was walking around taking pictures and stuff. He walked in at 2am with so much energy and so excited, and he let me know that he was going to beat me up.

"He was making fun of me saying harmless stuff like: 'Oh, you think you're so bad, you got all of those muscles, but I'm still going to beat you up'.
"I love the fact that he was excited to beat me up, it was like an honour to have Mayweather talking bad about me.
"The first three rounds were great work, still talking trash back and forth to each other, and then in the fourth round he said: 'let's turn the bell off, we're going to spar until you quit'."
McGregor, meanwhile, retired from MMA in June but hasn't ruled out a potential return to boxing.

When asked about a rematch with Mayweather, the 'Notorious' told TMZ: "I would like to rematch him under boxing rules, again.
"And I believe I would win. Actually, there I go again with that fake humbleness. I know I would win!
"When I went into the fight, in the early rounds I was whooping him, in the early rounds. I went back to my corner after the first round and I said, 'This is easy!'... and then he had to switch up his style."
