A surprising win for Lens over Arsenal in the last round of games has thrown wide open a group that also comprises PSV Eindhoven and Sevilla. Arsenal will be looking to bounce back from that loss, the only defeat in 13 matches this season across all competitions, both Domestic and European league as well.
Arsenal manager Mikel Arteta is weighing up the possibility of starting his first-choice goalkeeper Aaron Ramsdale ahead of the new signing David Raya, who is still adopting the culture and game style of the Gunners.
Raya has been shaky for Arsenal so far and made a couple of big mistakes in the 2-2 draw at Chelsea in the Premier League, including letting a cross go over his head and into the net for one of Chelsea's goals.
Sevilla will host Arsenal, while Lens, the group leaders will welcome the last place of the group PSV on Tuesday night.
