Khaberni - Mikel Merino scored twice after a penalty successfully taken by Bukayo Saka in the first half, leading Arsenal to a 3-0 win at Slavia Prague's stadium.
With this victory, the "Gunners" maintained their perfect start in the Champions League with four wins out of four matches without conceding a goal.
English winger Saka put the Premier League leaders ahead in the 32nd minute at the Fortuna Arena after Gabriel's header bounced off the raised hand of Slavia captain Lukas Provod, and a VAR review confirmed the handball.
Merino, who replaced Swedish striker Victor Yogrith who was injured last Saturday, scored the second goal with a direct shot 36 seconds into the second half following an unmarked cross from Leandro Trossard.
He made the score 3-0 in the 68th minute with a header that found the net of goalkeeper Jakub Markovic after Declan Rice sent the ball into the penalty area.
Arsenal, which brought on Max Duman (15 years old) in the second half to become the youngest ever player in the Champions League, did not concede any goals in eight consecutive matches across all competitions, equaling the club's record set in 1903.
Slavia still has not won a match in the league stage of the continental championship and remains with two points.
