Big-punching Nikita Tszyu says it's "cool" fighting for regional titles as he prepares to take the next step in his explosive boxing career.
A former national super welterweight champion, Tszyu ( 9-0, 7 KOs) has relinquished that title and will fight fellow New South Welshman Koen Mazoudier for the vacant IBF Australasian and the WBO inter-continental super welterweight titles at ICC Sydney next Tuesday.
