I don't think he'll be able to achieve this sequence. But regarding his dismissal, thinking about it, he shouldn't be leaving any time soon. Even if he loses, he has a legion of fans. They may not go see him at the event, but his engagement on social media is still high and he's very active.
For sure this is the thing about Johnny Walker he has a great engagement and is pretty much dedicated to this kind of sport and getting into the boat with Khabib Nurmagomedov is a great experience for him just like Belal Muhammad and becoming a champion even though many are not satisfied with his win we can see that his takedowns is more refine now because of the training he received from Khabib for sure his mentality has changed towards his training and hopefully Johnny Walker would also become champion someday.
But Regarding the upcoming UFC London fight where Leon Edwards is picking Sean Brady as his opponent, I really don't know if Belal and Edwards have some beef for each other but for this upcoming fight, I think I would be picking Sean Brady, Carlos Ulberg, and Alexia Thainara but will still did some research for their previous fights.
