At least, that's what we think he said.

The Spider was hanging at The Grove in L.A. when we brought up Khabib -- and asked what he thought of the Khabib's violent rise up the ranks.

"Khabib is great, he's amazing!"

There was a lot of overall praise for Khabib ... including this: "I believe Khabib come the best fight in the sport."

Obviously, Silva is from Brazil and English isn't his first language -- so, some of the things he says are a little more tough to understand than others.

We think he meant, "I believe Khabib can become the best fighter in the sport."

Either way, Silva's a fan -- and really wants to see him fight Conor McGregor.
