Mendonca trains at Chute Boxe, the same gym as Charles Oliviera and Anderson Silva in Brazil. This gym breeds beasts and the fact that he's been training there awhile holds weight on its own. Mateus is undefeated and won his last 6/9 fights by finish including his last 2 of 3. On the other hand, you have Ashiek Ajim, who starts his fights swinging. He has knocked out his last 3 guys in the first round, but hasn't fought someone of Mateus' caliber. The one time Ajim lost was because someone survived a round with him and he gassed out which turned into him getting finished. I bet Mateus withstands his early storm and gets a finish in round 2 or 3.
