Digital Oil Painting tribute for the "G.O.A.T." Superfight for the sport of Mixed Martial Arts. Conor "Notorious" McGregor (Irish MMA Legend) vs. Anderson "Spider" Silva inside the Octagon would easily help determine the Greatest of All-Time in Mixed Martial Arts in a Superfight of Superfighters, both multiple Championship belt holders best-in-class and multiple-classes. Dana White will need to pay these men what they are truly worth to make it happen.  Silva wrote on Instagram: “I have a huge admiration for the great athlete that Conor is and I believe this super fight would be something historic for the sport, neither of us has anything else to prove. “I believe UFC and (MMA) fans would like to watch this great martial spectacle, testing my martial skills against him would be fantastic.”McGregor instantly accepted the offer as he took to Twitter to state he would be willing to fight the 45-year-old up at middleweight, despite having never fought above the 170lb welterweight limit.
