Derevyanchenko's sparring partner: Sergiy is a complete fighter

On October 5 Gennady Golovkin (39-1-1, 35 KOs) could become a middleweight champion again. The vacant IBF belt will be at stake in the fight of GGG against Sergiy Derevyanchenko (13-1, 10 KOs), and both opponents are serious about winning.

In preparation for the fight with GGG the Ukrainian took advantage of the help of the other ward of his trainer Andre Rozier, the Puerto Rican Edgar Berlanga (12-0, 12 KOs), the middleweight prospect. Berlanga in a recent interview said that he was impressed with the boxing skills of Derevyanchenko.

"Sparring with Sergei had been an honor and a great experience for me. I am convinced that he will be able to shock the world in his fight against GGG. I really got a lot of things from sparring with him and a lot of confidence. He has incredibly good skills. I understand why people think that he can beat Golovkin on 5 October. He is a complete fighter", Berlanga said.
