Arsenal equalled a 122-year-old club record of eight successive games in all competitions without conceding a goal as they swept past Slavia Prague 3-0 on Tuesday to go top of the Champions League with four wins out of four.
Mikel Merino, replacing injured striker Viktor Gyokeres as a makeshift forward, scored twice in the second half after England winger Saka had put the Premier League leaders ahead in the 32nd minute.
Arsenal, who brought on 15-year-old Max Dowman in the second half to become the youngest-ever player in the Champions League, have now also won their last 10 games in a row and looked unstoppable at the Fortuna Arena.
