Ahead of the fight, Santos said in an interview with MMA Fighting that he drew inspiration from teammate Charles Oliveira's journey in the UFC:“[The UFC championship] is the item we all dream about. Every fighter, every athlete. To have the belt [when Oliveira was the UFC lightweight champion] and be able to touch it, put it on your shoulders and know that your friend and teammate made it, it motivates you even more. Like, you know it’s possible. With determination, focus and discipline, you can get there, too. It gives me strength to continue believing."
