Joshua Buatsi sent a message to his Olympic light-heavyweight rivals by producing a devastating knockout of third seed Elshod Rasulov to cruise into the quarter-finals.
Having halted Uganda's Kennedy Katende in his opening bout, the 23-year-old Buatsi lit up Rio once again as he out-muscled the third-seeded Elshod Rasulov before producing a truly ruthless finish in the final round.
Buatsi, who is with the South Norwood & Victory Boxing Club, began positively and immediately looked to establish his rangy orthodox jab - eventually adding a right hand that seemed to momentarily disorganise his opponent.
