:(In the first round of Champions League group fixtures, Borussia Dortmund will make the trip to Turkey to take on Besiktas on Wednesday.
The hosts sit at the summit of the Turkish top flight after four domestic games and earned automatic qualification for Europe's elite competition by winning the Super Lig title last season, while the German outfit will look to build on last year's Champions League campaign, as they reached the quarter-finals.
Besiktas earned qualification for this year's Champions League group stage after winning the Turkish Super Lig for the 16th time last season, collecting 80 points as they pipped Galatasaray based on having a slightly superior goal difference.
However, they did not enjoy a successful continental campaign, firstly being knocked out of Champions League qualification following a 3-1 defeat to Greek outfit Paok.
The Black Eagles then dropped into the final qualifying round for the Europa League, meeting Portuguese side Rio Ave, and they lost 5-3 in a penalty shootout after a 1-1 draw, depriving the Turkish giants of any further European football for the remainder of the season.
They now return to Champions League action this year on the back of a strong start to the domestic season, collecting 10 points from their opening four games without conceding a goal, and they most recently picked up a 3-0 home win over Yeni Malatyaspor thanks to a Michy Batshuayi brace and a Georges-Kevin N'Koudou goal.
Sergen Yalcin's side will now look to build on their strong start with what would be a crucial result to kick off the Champions League group stage, although they face a tough test against Borussia Dortmund.
The visitors also earned automatic qualification for this year's tournament, as they finished third in the Bundesliga last season, while also enjoying a strong run in the Champions League.
Der BVB cruised through the group stage in impressive fashion, collecting 13 points from six games to finish top and book their spot in the round of 16.
The German side then met Sevilla in the first knockout round, and a Mahmoud Dahoud goal and an Erling Braut Haaland brace saw them take a narrow 3-2 lead into the second leg, before another Haaland double ensured they drew the second leg 2-2 and progressed with an aggregate victory.
They were handed a particularly tough quarter-final draw against Manchester City, and after a 2-1 away defeat, Jude Bellingham put them ahead in the home leg, only for Riyad Mahrez and Phil Foden to get on the scoresheet and seal a 4-2 aggregate win for the Citizens, despite a valiant effort from Die Schwarzgelben.
Now under the management of former Borussia Monchengladbach boss Marco Rose, the Dortmund outfit have earned nine points from their first four league outings, most recently winning a dramatic clash 4-3 away at Bayer Leverkusen.
Goals from Florian Wirtz and Patrik Schick, either side of a Haaland finish, saw the hosts go into the break with a lead, and they retook that through Moussa Diaby after Julian Brandt's equaliser, only for the game to take another twist as Raphael Guerreiro drew Der BVB level and Haaland converted a penalty to fire his side to an eye-catching win.
They now head into the continental competition with the hopes of starting with a victory on their travels, with Rose's men setting their sights on another run deep into the tournament.
