I want to thank my team, without them I wouldn’t be where I’m at. I want that belt! We stuck with the game plan. I’m a pressure fighter. I worked on sitting down on my punches and I proved that I have great power when I do that. It’s amazing to have this support from the Polish fans. It definitely gives me extra energy.”
