A late Filip Ugrinic penalty gave Young Boys a crucial 3-2 first-leg lead over Galatasaray in their Champions League play-off tie after an enthralling contest in Bern.
Ugrinic scored from the spot after Abdulkerim Bardakci was sent off for a handball in the penalty area following a VAR review.
A Michy Batshuayi brace had looked to have boosted Galatasaray s hopes of reaching the Champions League s new league phase, dragging the visitors level after Joel Monteiro scored either side of half-time.
However, Ugrinic s 86th-minute spot-kick gave the Swiss side the advantage as they bid to reach the Champions League proper for a second straight campaign.
Galatasaray remain in the tie ahead of next Tuesday s second leg, though, and will look to hit back in front of a boisterous home crowd in Istanbul.
Schluss im Wankdorf: YB gewinnt das Playoff-Hinspiel zur Champions League 3:2. Am kommenden Dienstag kommt es in Istanbul zum Rückspiel.

Data Debrief: Batshuayi shines despite Gala defeat
Despite the disappointment of a first-leg loss, Batshuayi showed his quality after coming off the bench, scoring twice despite having just three touches inside the opposition box.
Monteiro matched him by scoring a brace for Young Boys, also creating three big chances, two more than any other player on the pitch.
