UFC Legend Georges St-Pierre Names His Pick For The 'Best Fighter On Earth'
Lightweight champ Khabib, 31, holds an MMA record of 28-0 and is hoping to extend his undefeated streak with his upcoming clash against Justin Gaethje at UFC 254 on 24th October.
But the 'Eagle' has been vocal about facing 'GSP' in April 2021 amid rumours he will retire after his 30th professional MMA fight.
'GSP,' who retired from MMA in 2019, believes that he is the "best" fighter currently active in the world.
The 39-year-old Canadian superstar told BT Sport: "Khabib right now, I believe, is the best fighter on the face of the Earth.
"On the face of the planet, he is the best right now."
'GSP,' who recently revealed his pick for the best heavyweight boxing performance of all time, has been heavily linked with a UFC return to face Khabib in a dream super-fight.
However, the UFC legend has doubts about cutting weight to 155lbs and it affecting his performance.
"It's tempting, and I still train hard," he said.
"Now, it's COVID, so it's illegal to train combat sports here. I train hard, and I feel I'm at my best. But the fighter is always the last one to find out when your time is up. I don't know.

"It takes three parties to make a fight: it takes one opponent, another opponent, and the organisation.
"And I don't know if the organisation would want that. I run away with welterweight, I run away with the middleweight. They surely don't want me to run away with the lightweight.
"And I'm 39 years old. I don't think I could go to 155 [pounds] without my performance being compromised."
'GSP' added that he has "never been a fan of cutting weight" and is "afraid of the long-term consequences."
He continued: "Khabib is fighting at 155, but I believe he's heavier than me.
"He walks around at a heavier weight. He's younger than me, so he can fluctuate weight better.
"I've never been a fan of cutting weight, so I never did it. I mean, I lost weight, but I didn't lose much weight compared to most of the guys. I'm afraid of the long-term consequences.
"And physically, I'm very fit. I don't have a lot of water retention and fat when I'm around at my walking around weight."
