If you like watching Sergey Kovalev fight then you guys might enjoy watching this Russian fighter as well. He's an old school fighter who fought during the 90's, mostly in Japan, and was a Flyweight Champion. He is pretty much like Sergey Kovalev stylistically although less aggressive and more technical, but still a powerful puncher. http://www.youtube.com/watch?v=bHMYpPHmR6I http://www.youtube.com/watch?v=PlA1XaMraRI
Not exactly a Kovalev, but I rank him amongst the elite ATG flyweights, below Canto-Villa, same as Wilde
I would have loved to see a match between Roman Gonzalez and Yuri Arbachakov. Arbachakov was probably one of the most graceful, elegant fighter @ flyweight. What a fight that would have been.
