Match preview
After a successful 2023-24 Super Lig campaign that secured a Conference League qualification spot, Istanbul Basaksehir appear to be picking up where they left off last season.
The Grey Owls secured their place in the main draw of Europe's third-tier cup competition with a 2-0 win over St Patrick's Athletic F.C. on home soil last Wednesday.
Cagdas Atan's men will face Copenhagen, Cercle Brugge, and Celje away, while they will host Heidenheim, SK Rapid, and Petrocub in the new group stage format.
Back in the league, Basaksehir secured their first league win of the season with a 4-2 victory over Alanyaspor on August 18, which has left them in fifth place despite playing one fewer game than most teams.
Unbeaten in their first eight games across all competitions this season, the Grey Owls are heading into this fixture filled with confidence - as they have also lost just once in their last 10 league games dating back to the previous campaign.
Both fixtures between these sides ended 1-0 in favour of the team at home in either leg, with Basaksehir securing a win at this venue, while Antalyaspor secured victory at Antalya Stadium.
Meanwhile, secured their first win of the season with a hard-fought 3-2 comeback victory over Hatayspor at the Antalya Stadyumu last Sunday.
Carlos Strandberg's first-half brace had left the Scorpions trailing at the break, but a lifeline came when Hatayspor were reduced to ten men in the 51st minute.
Thalisson Kelven ignited the comeback with a goal on the hour mark, before Moussa Djenepo restored parity five minutes later - however, they left it late before clinching all three points when Braian Samudio converted from the spot to complete the turn around four minutes into stoppage time.
It was the first competitive win under new manager Alex, who took over the role at the start of the season - a victory he will hope serves as a turning point to his poor start.
The Scorpions are, however, on a poor run on the road, having gone winless in their five away games dating back to last season, losing four of those matches while drawing one.
