Lomachenko said he believes that his opponent Marriaga is a tough fighter who has a big desire to fight, according to fightnews.com.
"It's hard to get fights and I am frustrated we wanted the fight with Salido but we settled with Marriaga. I think he is a good tough fighter with a big desire to fight. When he accepted this fight right away I knew it would accept it. It shows he has the balls to fight," Lomachenko said.
The fight between Lomachenko and Marriaga will take place at the Microsoft Theater arena in Los Angeles on August 5.
