Porto, Portugal: Arsenal manager Mikel Arteta kept faith with the team that thrashed Burnley 5-0 at the weekend for Wednesday's Champions League last 16 first leg at FC Porto.
Leandro Trossard leads what has been a free-flowing attack of late with Bukayo Saka and Gabriel Martinelli nominally starting to the left and right of the Belgian.
Jakub Kiwior continues to fill in for Oleksandr Zinchenko at left-back as the Ukrainian recovers from a calf problem. Gabriel Jesus is still out with a knee injury.
Wendell returns from a domestic ban to start on the left side of Porto's defence with Nigeria international Zaidu Sanusi sidelined by a knee injury picked up last weekend.
Arsenal are playing their first Champions League knockout tie for seven years. They last made it to the quarter-finals back in 2010.
