McGregor saw his hopes of beating Nurmagomedov fade on Saturday night with the Irishman tapping out in the fourth round.
Many were surprised by the 30-year-old’s failure to rattle his opponent, who eased to victory in front of an expectant Las Vegas crowd.
Bisping, though, believes Conor McGregor threw the fight by giving up.
“Look, what happened towards the end is that Conor gave up, because the choke wasn’t even under the chin; it wasn’t on the neck,” Michael Bisping said on the UFC 229 post-fight show.
“But it’s easy to sit here and say he gave up when you’re tired and when you’ve been pounded for four rounds.
“Let’s not forget that, in that second round, Khabib put it on him bad.
“When you get to round four, the choke doesn’t need to be perfect, the technique doesn’t need to be perfect. It sucks.”
McGregor, whether he quit the UFC fight or not, is determined to fight again.
But Dana White has questioned whether a rematch between the Irishman and Khabib is even possible.
“We have to see what happens with the Nevada State Athletic Commission (before discussing a rematch),” White told MMAjunkie at the UFC 229 press conference.
“Not just the commission – there’s going to be fines and God knows what else.
“Can these guys get visas and get back in the country?
“And I mean Khabib. We’ll see how this thing plans out.
“I’ve been doing this for 18 years and on the biggest night ever, I couldn’t be more disappointed.
“You know me, I’m always mad at everything.
“I’m not even mad. I’m just disappointed.”
