The second leg promises even more drama after St. Gallen secured a narrow 2-1 victory in Switzerland. Holding a one-goal advantage, the visitors travel to Lisbon knowing they are just one positive result away from a famous qualification, while Benfica must overturn the deficit in front of their home supporters at the Estádio da Luz.

Despite trailing on aggregate, Benfica remain overwhelming favourites. Marco Silva's squad possesses significantly greater European experience, superior individual quality, and far more depth than their Swiss counterparts. With qualification on the line, the Portuguese giants are expected to dominate possession from the outset, applying sustained pressure in search of an early breakthrough that could quickly change the complexion of the tie.

St. Gallen proved in the opening meeting that they are capable of competing at this level. Their aggressive pressing, disciplined organization, and clinical finishing allowed them to punish Benfica's mistakes and take a valuable first-leg lead. That result has given the Swiss side genuine belief heading into one of the biggest matches in the club's recent history.

However, playing away at Benfica presents an entirely different challenge. The atmosphere in Lisbon has long been one of the club's greatest strengths, and the home side traditionally raises its performance in European nights at the Estádio da Luz. Should Benfica strike early, momentum could rapidly swing in their favour, forcing St. Gallen to spend long periods under intense pressure.

The visitors, though, have every reason to remain patient. With the aggregate advantage in hand, they can afford to defend in a compact shape, frustrate Benfica's attacking rhythm, and look for opportunities to counterattack. One well-executed break could dramatically increase the pressure on the hosts, who would then require multiple goals to stay alive.

For Benfica, elimination at this stage would represent a major disappointment, ensuring there will be no shortage of urgency or commitment. The match offers an ideal opportunity for the Portuguese side to demonstrate both their quality and their resilience in a high-pressure European contest.

All signs point toward an entertaining battle. Benfica are likely to push forward relentlessly, using sustained possession and attacking width to create openings, while St. Gallen will rely on defensive discipline and quick transitions to protect their slender advantage. Although the Swiss side have already shown they can compete, Benfica's home advantage, superior squad, and European pedigree make them the stronger favourites to complete the comeback and secure qualification.
