Villanueva is being groomed to be another superstar from the Philippines as former multiple world champions Manny Pacquiao and Nonito Donaire get closer to retirement.
Tete has left 20 of his 24 victims counting the stars. He has lost only three fights.
But Tete was stopped in five rounds by Moruti Mthalane for the IBF flyweight belt in 2010.
Meanwhile, Villanueva is an average puncher who has knocked out only 16 of his 30 opponents. He is yet to be dropped. His loss to McJoe Arroyo in 2015 was a controversial technical decision.
Tete is rated No2, a spot below Villanueva, in the WBO bantamweight rankings.
WBO champion, Marlon Tapales, will defend against Shohei Omori in Japan on Sunday, and the victor will later have to face the winner between Tete and Villanueva
