Beşiktaş will face a demanding mix of Bundesliga, Ligue 1 and Premier League opposition in the Europa League, while Trabzonspor will begin its Conference League campaign against clubs from six different countries after the league-phase draws were held Friday in Monaco.
The draws at the Grimaldi Forum set the European schedules for the two Turkish clubs, with Beşiktaş remaining in UEFA's second-tier competition and Trabzonspor dropping into the Conference League after its Europa League playoff exit.
Beşiktaş, drawn from Pot 4, was paired with Bayer Leverkusen of Germany, Olympique Marseille of France, Union Saint-Gilloise of Belgium, Celtic of Scotland, Crystal Palace of England, Omonia of Cyprus, Hapoel Be'er Sheva of Israel and Hoffenheim of Germany.
The Black Eagles will host Marseille, Union Saint-Gilloise, Crystal Palace and Hapoel Be'er Sheva at Tüpraş Stadium in Istanbul.
Their four away matches will be against Leverkusen, Celtic, Omonia and Hoffenheim.
