He is an aggressive young fighter. He came to try and prove something, which is good in some ways. I think he learned a lot from sparring with me. He got confidence knowing that if he can spar with me he is able to match it with anyone. He is strong, but he does not have full experience yet, but potentially, he is very good. He has great ambitions to go forward. With more experience, he will become more confident in himself as he learns new tricks. He needs to keep learning from each fight. Kostya Tszyu
