With a quick submission by Makhachev against Oliveira, I think that's the reason why people think Makhachev will win against Volkanovski. Although Volkanovski was already fight everyone in his weight and remain undefeated, he seems can't compete against Makhachev. Volkanovski is a kickboxer, he will get a trouble since Makhachev is a wrestler, even Oliveira is a good wrestler too but can't survive for complete 5 rounds.
The Level of pressure Islam Makhachev on this wrestling surely far exceeds Oliveira's wrestling but on Volkanovski's part I really think he is ready and has now a decent takedown defense but surely this is the 1st time Volkanovski is facing a Dagestan wrestler, he surely faced many wrestlers in his career but not a Dagestan wrestler and Islam Makhachev is in a different level of caliber when it comes to Combat Sambo Dagestan wrestling type of wrestling, with this kind of wrestling the cage wall is Makhachev's friends while some wrestler it is an obstacle for them, it is pretty much different and the way they train their strength and grip is surely impressive enough, so for me Islam Makhachev all the way,
We know how strong Makachev is since he has been winning these past years because of his high skills and experience when it comes to wrestling and he is giving his opponent a really hard time when he looked them by submissions. But we also know Volkanovski is the number one rank in their division and might gonna be hard to beat because he is different from other fighters he fought before. It might be hard to believe but, obviously, most people are cheering for Volkanovski because Islam Makachev has been demolishing their idols and they wanna revenge using Volkanovski.
The problem with wrestlers is if a fighter is a pure striker he doesn't stand a chance against a wrestler, sometime they tend to get preoccupied when the takedowns are coming and their technical view with the fight is always get cautious against a takedown, this would surely cause strikers fighting technique, but in Alexander Volkonovski's case he can surely wrestle but he tends to be more technical on striking, and a good reflexes, but against Islam Makhachev that surely has a different level of wrestling that Volkanovski have ever face this is going to be a problem for Volkanovski,
