Tuesday's Champions League tie will mark the first-ever competitive meeting between Athletic Bilbao and Arsenal, although the two clubs did contest this year's Emirates Cup in pre-season.
That North London battle was a forgettable affair for the Spanish side, who were beaten 3-0 thanks to goals from Viktor Gyokeres, Bukayo Saka and Kai Havertz and never looked like troubling the Gunners on the day.
However, Athletic ought to be more fired up for their first Champions League game since the 2014-15 season, where they finished third in the group stage, and their only other appearance in the competition since its rebranding came in the 1998-99 campaign.
Meanwhile, Arsenal seek back-to-back wins after easing past Nottingham Forest 3-0in Saturday's Premier League contest, and they have lost just two UCL group/league phase away games over the past two seasons, to Lens and Inter Milan.
