Referencing reports from Turkish media during the transfer window about serious interest in Oskar Pietuszewski from Beşiktaş, Łukasz Masłowski, sporting director at Jagiellonia Białystok, stated in an interview with 'Piłka Nożna' that there was no offer for the player in the summer. Masłowski added that the club did not conduct talks because they did not want to. He also stated that no one was interested in selling Pietuszewski in the summer and that no one is currently working on his departure.

Besiktas is reportedly interested in Oskar Pietuszewski, a player considered highly desirable in the transfer market. In addition to Besiktas, Anderlecht, VfL Wolfsburg, and AS Monaco have also shown interest in the 16-year-old Polish talent. Despite this significant attention, Pietuszewski has recently renewed his contract with Jagiellonia Bialystok, keeping him with the Polish club until 2027 and indicating his stay for the upcoming season. His agent, Mariusz Piekarski, mentioned that there have been numerous offers, highlighting that the interest comes not from mid-tier clubs but from top European leagues, which suggests a potential future transfer at an elite level.
