Who Should Khabib 30th and maybe last fight be

This thread is to talk about what should be Khabib Last fight, Even though he fighting with Justin Gaeche in a few week, We all know Khabib gonna win because Khabib is pretty much Unbeatable. The Fighter you can chose are

a) GSP
b) Conor Mcgregor
c) Tony Fergoson
d)Usman
e) Other

Im personally leaning Usman because 
1. It make me care because going up a division will make Khabib seem beatable  so I can finally root for him
2.He can become Champ Champ for legacy even tho who care about champ champ
3. He should beat him because Khabib is a better fight because Khabib Mauls and Usman stall for a simple breakdown off that fights
4. Usman will no longer be champ :)

Getting GSP to get out of retirement would be the first challenge, but I would love to see that fight! Conor is overrated(yawn). It will go down in history that Tony and Khabib will never fight (cursed). And Usman, has yet again bailed out on fighting Burns. I don’t think he wants to fight anyone he thinks will defeat him, so hard pass. 

Of course Khabib would destroy GSP. No question about that. I mean come on the dude used to wrestle a bear as a kid... nuff said. 

GSP would be cool but I’d personally like to see Khabib vs. Ferguson. 

@Hippie No, it is cursed, never going to happen.. just forget about it. Hold on to your hopes and dreams boys and girls, because the chance of seeing that epic fight is fading away...

Yeah that sux!  @ Chelsey

See, even Khabib wants it to be his 30th...

GSP - Won't come out of retirement to get destroyed
Conor McGregor - Does anyone really want to see this fight?
Tony Ferguson - This would be cool but I'm not hopeful 
Kamaru Usman - It would be interesting but I can't see this one happening either

My choice - Islam Makhachev


I could still see Khabib winning this fairly easily but it would be an interesting test for Makhachev.

@Stephen Terry

I don't think Islam Makhachev would fight Khabib, because they're teammates at AKA and they're friends.

@tepid55

That's a good point but at the same time seeing as it would be Khabib's last fight he might find it fitting to end by fighting a good friend and fellow Russian in a competitive yet at the same time, sorta exhibition bout. His title would be on the line for sure but he'd win fairly easily and probably would be able to have a bit of fun fighting a friend while doing so. Plus it would be a good learning experience for Makhachev as I'm sure they've fought countless times in training but training and competitive fights are very different ball games and regardless of the result, I'm sure Makhachev would be able to take something away from it so Khabib would also end his career helping a teammate as well.

I'd see this as a win-win situation for both fighters.

This is pretty easy

Shannon Ritch

If Conor beats Poirier it'll almost definitely be him. It's not the fight I want to see but from a business standpoint I guess it makes the most sense. 
Poirier is a whole different beast now though from when they first fought, so it's not a give in that he'll even get past him to set up the Khabib fight.
