Despite Arsenal's 1-0 victory over Sporting in Lisbon, the Portuguese team still has a chance to cause an upset in the second leg of their Champions League quarter-final. Pepa, a seasoned Portuguese coach, analyzes the key tactical aspects of the first match and explains why Rui Borges' Sporting side could still turn the tables at the Emirates Stadium. The first leg was a closely contested game between two top-notch teams, with few clear scoring opportunities but plenty of interesting tactical and technical moments.

Arsenal, currently leading the Premier League and boasting an impressive Champions League campaign, demonstrated their ability to maintain a compact 4-4-2 shape without the ball and effectively close down central spaces. They also showed a strong recognition of pressing triggers, often resulting in near man-oriented pressing behaviors, which allowed them to recover the ball high up the pitch. In contrast, Sporting delivered a very positive performance considering the quality of their opponent, with their dynamic defensive structure and strong character enabling them to neutralize Arsenal's intentions, except for the goal conceded.

To turn the tables in the second leg, Sporting will need to remain true to themselves, imposing their strengths and being more focused, consistent, and effective than in the first match. The return of injured players, such as Morten Hjulmand, and the importance of set-pieces could be decisive factors in the match.
