The last three UCL two-legged ties to be determined via a penalty shootout

In fact, Arsenal's victory against FC Porto in the 2023/24 Round of 16 was the first to have taken place in the tournament for eight years.

The Gunners hadn't reached the last eight of the competition since way back in 2010, but they looked on course for the quarterfinals when Leandro Trossard gave them the lead on the night just prior to halftime. However, the second goal never came. The Portuguese side had already locked up a 1-0 victory in the first leg, so the tie was level at one goal apiece on aggregate. Neither side could make the breakthrough, forcing the contest all the way to the shootout for the first time since the away goals rule was scrapped.

Once there, Martin Odegaard, Kai Havertz, Bukayo Saka and Declan Rice all kept their nerve, allowing shot-stopper David Raya to become the hero with two penalty saves.
