Even if skill-wise in the octagon they are very close.
Does anyone think that Arman (or anyone?) outworks Islam in training, in preparation, etc.
We've never been exposed to Islam melting under pressure or adversity in the cage. Do you truly think Arman is the fighter to push Islam that far?
If there was training footage of Khabib pushing Islam to that kind of failure then I might believe it's possible in the cage on Saturday but I don't think that is the case.
Could he get caught? Sure. But that's fighting. Anyone could get caught.
