Khabib simply told - "Islam is a champ, he must be ready for everyone. If King Kong fits in 170lb, bring him in" 
The champ isn't devastated after the match and his opponent shouldn't be moving like he received no damage. Don't you remember in what conditions Islam was compared to Volkanovski after the match? There are a lot of people who think that Volk was robbed and lots of people support rematch but it's bad that Volk has almost no time to prefer and he still took it, I hope he wins.Uh nope... Khabib is def in Makhachev's camp and will def be in his corner.

Translation: "Work! Work! Work! Do not be distracted!"
This is hard to understand for non-Russian speaking people, but this video or this fragment already became a meme. That is used in jokes like "hey boss, can I have a day off tomorrow? and the answer is this video fragment" and etc
So I guess the original plan for Chim was to fight Costa then fight somebody in 185's top 5 then a title fight.
Haven't they announced that the winner of Chimaev Vs Usman will get a shot against Strickland? I've heard that somewhere but don't know if it was only a rumour or confirmed information.
I guess UFC are too cautious to make such announcements.
