Moses Itauma took a giant step forward in the direction of future superstardom on Saturday in the most difficult flight to date of his two-plus years as a professional.

Dillian Whyte has won his last three fights since losing to Tyson Fury at Wembley Stadium but the main problem is those have come over the course of three years.

Itauma, 20, proved why he is one of boxing's hottest prospects as he knocked down Whyte, 37, with a powerful array of punches to stun the crowd in the Saudi Arabian capital of Riyadh.
