This round features a total of 60 teams, with 52 participating in the main path. Eight teams that were eliminated in the Champions League first qualifying round are competing in a dedicated champions path.
Turkish club Istanbul Basaksehir faced a challenging match, falling behind less than two minutes into their game against Viking. Sander Svendsen put his team ahead, suggesting a possible upset.
The hosts kept creating opportunities in the first half, as Joel Bell had a golden chance around the half-hour mark. Unfortunately for him, Basaksehir had enough defenders to block the shot.
Failing to capitalize on their opportunities, Viking ultimately faced consequences in the second half. Deniz Turuc equalized at the hour mark, followed by Christopher Operi scoring what turned out to be the decisive goal 11 minutes before the end. Davie Selke added a third goal in the dying moments, leading Basaksehir to a 3-1 victory as they head into Tuesday's decisive match.
In other matches, Slovenian team Celje, who reached the quarter-finals of the Conference League last season, dominated with a 5-0 victory over Lugano. Franko Kovacevic converted two penalties - one in each half - as the visitors capitalized on their opportunities in a convincing win over the team they eliminated in the round of 16 last March.
CS Universitatea Craiova scored three goals in the second half during their 3-0 victoryagainst Spartak Trnava. The Romanians, who made it to the semi-finals of the 1982/83 UEFA Cup, netted twice within three minutes shortly after the restart, taking a strong lead into next Thursday's decisive match.
Banik Ostrava and Austria Wien engaged in an exciting match in Czechia, where the hosts found themselves trailing just four minutes in. However, they managed to take a 2-1 lead into halftime, adding a third goal shortly after the restart.
The Austrians leveled the score in the 79th minute, and just when they thought they would secure a draw, Erik Prekop scored the winning goal, giving Banik a 4-3 victory and a slim advantage.

Anderlecht celebrated a 3-0 home victory over Sheriff Tiraspol, while Besiktas defeated St. Patrick's Athletic 4-1. Hibernian bounced back from their disappointment last Thursday with a 2-0 win against 10-man Partizan Belgrade. As for Levski Sofia, they narrowly defeated Sabah Baku 1-0 thanks to a last-minute goal from Branislav Rupanov.
In the champions path, FCI Levadia Tallinn triumphed 3-2 against Differdange 03 as the Estonians made their mark before the hour mark. That was also the final score in Moldova, where Milsami Orhei managed to defeat Virtus despite being reduced to nine men with seven minutes remaining. Still, Ime Ndon found a goal for his team just before the end of the 90 minutes, giving them an advantage for next week's second leg in San Marino.
