Kylian Mbappé scored on his competitive debut for Real Madrid as they beat Atalanta 2-0 in Warsaw to clinch the Uefa Super Cup. Mbappé, who completed a free transfer to Madrid in June after his contract at Paris Saint-Germain expired, lashed home from Jude Bellingham’s pass after Federico Valverde had given the Spanish champions a second-half lead. Madrid beat Borussia Dortmund 2-0 in the Champions League final in June and victory over Europa League winners Atalanta at the Narodowy Stadium secured a record sixth Super Cup success. Atalanta edged a goalless first period in which both sides hit the woodwork. Madrid defender Eder Militão’s attempted headed clearance from Marten de Roon’s cross looped on to the crossbar, while Brazil forward Rodrygo struck the bar with a shot from inside the penalty area. Mario Pasalic’s second-half header for Atalanta was superbly saved by Thibaut Courtois. Madrid broke the deadlock in the 59th minute when Vinícius Júnior brilliantly set up Valverde for a simple finish by picking him out from the byline. The Atalanta goalkeeper Juan Musso denied the Brazil forward a second and thwarted Bellingham soon after as Real took control. Mbappé made it 2-0 in the 69th minute after being teed up by Bellingham and Real comfortably saw the game out.
