Barao is 28-1-1, going unbeaten in his last 29 fights.
Along the way he has defeated former title contenders and champions Scott Jorgensen and Cole Escovedo.
But Barao has never faced anybody with the popularity and resume of Urijah Faber.
Faber is the former WEC featherweight champion and the only man to defeat Dominick Cruz.
But Barao comes into this fight with the confidence and skill set that could give Faber a run for his money.
Barao trains with some of the best fighters in the world at Nova Uniao.
One of which is UFC featherweight champ Jose Aldo.
Aldo gave Faber one of the worst beatings of his career by punishing his legs for five rounds.
For Barao to have the same success, he will have to be quicker than Faber, and be prepared to have excellent wrestling defense.
Barao will also have to be on the defensive on his feet.
Faber can be a quick striker and uses his hands to set up takedowns and throw his opponents off.
He can also be excellent in the clinch.
Barao will have to try to avoid the constant pressure that Faber will try to put on him and pick the right spots to strike.
If Faber is somehow able to get Barao on his back, then Barao will have to work hard for a submission or be able to get himself back up.
Faber comes into this bout the stronger and more experienced of the two fighters.
But if Barao can be a step quicker with his striking and have excellent defense, he will take home UFC gold.
