Konstantinos Karetsas Shines in Borussia Dortmund Debut

Konstantinos Karetsas needed only one night to announce himself in Germany.

Borussia Dortmund lost the German Super Cup 2-1 to Bayern Munich at Signal Iduna Park, but the scoreboard barely told the story of the 18-year-old’s debut. The Greece international, signed this summer from Genk, played with the swagger of someone who had been on this stage for years, not minutes.

From his first touches, the crowd reacted. Karetsas dropped into pockets, turned away from pressure and threaded passes through tight gaps. His dribbling drew defenders in, his playmaking opened angles that hadn’t been there a second earlier. Several times, the famous Yellow Wall rose not for a goal, but for the way their new No. 10-in-waiting treated the ball.

Dortmund paid around 30 million euros to bring him from Belgium. On this evidence, they didn’t buy a prospect. They bought a player.

Kompany takes notice

The performance didn’t just light up the stands. It followed Vincent Kompany down the corridors.

According to “Bild”, the Bayern Munich head coach spoke glowingly about Karetsas after the final whistle. Dortmund correspondent Michel Schroder recounted how he bumped into Kompany in the bowels of the stadium and asked him about the teenager. The Belgian coach didn’t bother to hide what he thought.

Kompany described the Greek playmaker, who grew up in Belgium and came through at Genk, as “very good” and told Schroder to keep a close eye on him. It wasn’t the polite praise managers sometimes hand out after a one-off display. The way he spoke, Schroder noted, suggested a coach who had tracked Karetsas for a long time and genuinely “likes him a lot”.

When a Bayern coach walks away from a Super Cup thinking about an 18-year-old in black and yellow, that says plenty.

A track record, not a one-off

Karetsas’ emergence in Dortmund didn’t come out of nowhere. He had already forced his way into Genk’s first team at a strikingly young age and left a strong imprint on last season.

In the Belgian league he delivered 11 assists and scored twice, impressive numbers for a teenager operating in the final third. On the European stage he carried that form into the Europa League, adding five more assists in just 11 appearances. Those figures turned heads across the continent and justified Dortmund’s decision to move decisively in the summer.

Now, with one high-profile outing in Germany, those numbers suddenly have a face and a style attached to them.

A new favourite in the making?

Inside the club, optimism is already building. Schroder believes Karetsas has the tools to grow into one of Dortmund’s leading stars in the coming years. The technique is obvious, but so is the personality: he demands the ball, he tries things, he plays on the front foot. That combination tends to resonate quickly in this city.

A fan favourite? That may not take long either if he keeps playing with this kind of courage in big games.

He couldn’t change the result against Bayern. He couldn’t hand Dortmund the Super Cup. What he did, though, was send a clear message on a night of defeat: there is a new playmaker in town, and the rest of the Bundesliga has been warned.
