Though defending was now undoubtedly Porto’s priority, the team still looked dangerous on its occasional foray forward with Francisco Conceição testing Raya with a low shot after a swift counterattack.

Arsenal continued to press and had chances to win the tie through Bukayo Saka and Odegaard, but there was an increasing inevitably that the tie would be going to extra time.

After a riveting 90 minutes, extra time was largely a non-event, with the highlight coming when Kai Havertz pushed Porto manager Sergio Conceição to spark a tussle on the touchline.

Arsenal’s home advantage then proved pivotal in the penalty shootout. Faced by a wall of noise and twirling red and white scarves, Wendell and Galeno were unable to maintain their focus and the duo’s missed penalties proved costly for Porto as Arsenal fans serenaded their manager with one final rendition of ‘Super Mik Arteta.’
