I would not agree with you on it. I think Izzy has a chance and in my mind it's 50/50. If Izzy can drag him down and do a bit of wrestling in first round I think Pereira will go out of gas in later rounds. And this is likely to happen same like landing some big shot from Pereira. Cause of that I think it's 50/50.
I would not give 50/50 chance in fight between two guys with one of them beating the other one three times before, and it was TKO two times. 
It's clear to everyone who the favorite is in this fight, but surprises can always happen.
Once again, I'm worried for Izzy. However, I do think the pressure is largely off. He's already lost his belt, and now it's all about proving it to himself.
I dont think his problem was pressure, his problem is Pereira, that is why he lost so many times against him.Pereira fighting style is kryptonite for Adesanya, and only chance he can have is in case if Pereira gets injured before or during the fight.
I hope I am wrong and he is going to give his best but I dont think it will be enough to beat this guy.
Heard some words swirling around that Adesanya trained a lot in wrestling coming into the event. I'm not sure if it's a wise move as Pereira is a huge heavy guy.
We all saw what happened when he tried doing that with Jan Błachowicz 
He likes taking risks, but repeating this against Pereira would be suicicide.
This are my bets for this event main card:
Alex Pereira by decision.
Gilbert Burns, fight wont go to distance.
Adrian Yanez
Kevin Holland
Christian Rodriguez, but this can go eaither way.
Chris Curtis
