Tagoe, popularly referred to as Gameboy in boxing circles, described himself as the greatest lightweight fighter of his generation and vowed to win a world title again under his new American promoters, LouDiBella Entertainment, moments after being decorated with the titles.

The Russian regained his strength in the ninth round and occasionally put his opponent on the back foot as he reeled on the ropes to get out of trouble and avoid falling to the canvas.
