Entering the second leg under pressure due to a recent decline in domestic form, Arsenal started the match well but could not maintain their early momentum. Sporting gradually asserted themselves and appeared the more assured team for much of the first half.

Francisco Trincao came close with an effort that went wide, followed by Pedro Goncalves missing the target from a narrow angle. Sporting’s closest chance before half-time came when Geny Catamo struck the outside of the post with a sharp volley, while Arsenal’s attacks remained ineffective and failed to seriously challenge goalkeeper Rui Silva.

In the second half, Sporting maintained their attacking threat, with Maximiliano Araujo firing narrowly wide shortly after the restart. Arsenal manager Mikel Arteta responded by bringing on Kai Havertz, whose introduction nearly yielded a goal when Noni Madueke's break into the box ended with a shot that struck the side netting under pressure.

As tension grew within the stadium, Arsenal struggled to find a decisive goal to secure the tie. Arteta was booked on the touchline amid the mounting pressure, as Sporting continued to pose a threat.

Arsenal finished the match strongly as the Portuguese team showed signs of fatigue. Leandro Trossard came the closest to scoring late on, heading against the post from a corner, but the match concluded in a goalless draw.

The result ensured Arsenal’s progression thanks to their first-leg advantage, setting up a semi-final encounter with Atletico Madrid. The match also marked Arsenal's eighth clean sheet of their European campaign.

For Sporting, the well-disciplined and confident display ended in disappointment as they missed the chance to reach their first Champions League semi-final, extending their difficulties in away matches against English teams.
