The Gunners are the only team in the current Champions League season still unbeaten (10 wins and 1 draw), and they secured a narrow 1-0 away win in the first leg in Lisbon. Opta Optimizer rates Arsenal's chances of reaching the semifinals at 77.7%, the highest among all quarterfinalists.
Furthermore, Sporting have won only two of their last 14 European matches against English clubs. It's important to note that Arsenal are conceding an average of just 0.45 goals per game in this Champions League, and just 0.33 away, making it extremely difficult for the Portuguese to recover.
With a home crowd at the Emirates Stadium, where Arsenal won 100% of their group stage matches, and Sporting forced to open up in search of goals, the hosts will have ideal counterattacking opportunities. Despite potential personnel losses in the Arsenal squad (including Martin Ødegaard's injury), the depth of their squad and solid defensive play allow them to expect a final victory with a scoreline that will secure progression to the next round.
