Yallyev has interesting features such as his ability to comfortably switch stances and is technically solid. However, he really hasn't fought anyone of note, has been a bit inactive. In addition to his very limited amateur career, hence its tricky to get a clear idea of him until he fights some more seasoned opponents. I think he is an above average puncher at least, but not enough to be seen as a 'big' puncher quite yet. I don't think he will be world champion but I could see him in the top 10 fighting for a world title at some-point at least. He has some potential but a lot of work to do.
