"The main reason why fighters end their careers is they don't want to make weight races anymore. When Khabib decided to retire, the UFC didn't want to accept that fact. They offered him a new contract, under it Khabib would have gotten a huge amount of money. But the UFC went the wrong way. If they had offered him to move up to welterweight, Nurmagomedov would have had another fight. But the promoters do not understand this," Sonnen said in a video on his YouTube channel.
Recall, Khabib finished his career in October 2020 with a record of 29-0.
