The London side asserted their superiority from the outset. England’s Noni Madueke opened the scoring in the ninth minute following a pass from Sweden’s Viktor Gyokeres, who then added the second in the 38th minute after exchanging passes with Spain’s Mikel Merino, giving Arsenal a 2-0 half-time lead.
Slavia Prague rallied in the second half, threatening Spanish goalkeeper David Raya’s goal on several occasions. Poland’s Wiktor Nowak eventually reduced the deficit in the 90th minute, converting a cross from Czech player David Jurasek, but Arsenal held on until the final whistle.
Spanish coach Mikel Arteta’s side moved to ten points from three wins and a draw, climbing to third in the standings. Slavia Prague remained on one point after failing to win for a 23rd consecutive Champions League match.
The European success builds on the Gunners’ narrow 1-0 Premier League victory over Liverpool, helping Mikel Arteta’s squad regain strong momentum both domestically and on the continent following their shock League Cup exit at the hands of Fleetwood Town.
