O'Malley thinks Khabib may have left because he didn't want to fight Oliveira

American UFC bantamweight fighter Sean O'Malley expressed the opinion that the former UFC lightweight champion Khabib Nurmagomedov ended his career due to unwillingness to intersect in a cage with Charles Oliveira.

“This is an interesting fight that I would like to watch. Everyone believes that Khabib destroys everyone in his path. I believe that Oliveira is the only one who could create problems for him.

Who knows, maybe it was for this reason that Khabib hung up his gloves on a nail. Maybe he looked at Charles and thought, "No, I don't want to fight this guy." I think Khabib vs Oliveira would be a huge fight," O'Malley said in an interview with the Canal Encarada YouTube channel.

Nurmagomedov ended his career in October 2020 after an early victory over Justin Gaethje.
