The north London side went into the second leg of the last 32 with a 1-1 scoreline and went ahead in the 21st minute through Pierre-Emerick Aubameyang after an incisive pass from Saka.
Right before the interval, the Portuguese side pulled level on the night after Diogo Goncalves scored with a stunning free-kick which nullified the Gunners’ away-goal advantage.
At the hour mark, Jorge Jesus’ side went ahead through Rafa Silva following a defensive blunder from Dani Ceballos, who gifted possession with a poor attempt to head the ball back to Bernd Leno. Silva rounded the goalkeeper before an easy finish.
Kieran Tierney came up with his first Europa League goal of the season to make it 2-2 on the night and 3-3 on aggregate in the 67th minute, but the Gunners needed another to progress to the round of 16.
It appeared that the Gunners were heading for a last-32 exit for the second season running, but Saka stepped up with a superb cross for Aubameyang at the back post, who nodded home from close range in the 87th minute.
Aubameyang redeemed himself after his poor showing during the away leg where he was guilty of missing some clear-cut scoring chances. However, it was Saka who earned much of the praise for driving the team forward and creating the winning goal.
Here are some of the reactions on Twitter.
Bukayo Saka has 28 goal contributions in two seasons which is more than any other teenager in the world.
