And another question, why does Merab always fight in Las Vegas his recent fights? I don't remember him fighting somewhere else recently.
The UFC performance institute (UFC PI) is located in vegas.
Many UFC fighters live and train there as they can receive free training, free meals, free supplements, free medical support & other benefits at the UFC PI.
Vegas is where the UFC has most of its infrastructure and amenities.
It is a great tourist and gambling destination. Which is why it was once called the fight capitol of the world.
There's also a PI in Mexico and one in China... And they're planning on building a couple more. They're gonna he in Africa and the other one could be in South America or Australia.
But yeah, I think the reason why Dvalishvili's matches are always organized in Las Vegas lately is because he's prolly the biggest draw for audiences located in the US right now with Topuria a close second and Aspinall third.
