Dortmund's Champions League Win Overshadowed by Karetsas Injury
Dortmund’s Champions League win in Spain stopped feeling like a football match the moment Konstantinos Karetsas went down.
The 18-year-old, making his debut on Europe’s biggest stage against Villarreal on Tuesday night, had just played a simple pass when something was clearly wrong. He raised his arm, signalled to the referee, then sank to the turf. Players from both sides immediately waved urgently for medical help. The stadium noise dipped into an uneasy hush.
Dortmund moved quickly to calm the growing anxiety. In an official statement, the club confirmed the problem was related to the midfielder’s circulatory system.
“Konstantinos Karetsas had to leave the field due to circulatory problems,” the statement read. “Kosta is doing well under the circumstances and is on his way to the hospital for further tests.”
The wording brought some relief, but only some. Images of a teenager in distress on his first Champions League appearance linger longer than any scoreline.
Dressing room concern, cautious optimism
After the final whistle, Gregor Kobel gave voice to what everyone in yellow and black was feeling.
“I hope and I think that everything is OK and I hope that he's back and fit with us soon,” the goalkeeper told broadcaster Amazon Prime.
No drama, no embellishment. Just a senior player hoping a young teammate’s night ends as a scare, not a turning point.
A €56m project under a dark cloud
Karetsas arrived at Signal Iduna Park in the summer as part of a bold reset. Dortmund paid around €30 million (£25.7m/$34.9m) to prise the former Belgium youth international from Genk, betting heavily on his ceiling and his temperament. Alongside him came fellow Greece international Giannis Konstantelias, a €26m (£22.3m/$30.2m) signing from PAOK.
Two statement deals. Two players earmarked not just for the future, but for the here and now of a Champions League campaign.
The plan has unraveled brutally. Konstantelias’ season was effectively written off last month when he suffered a serious ACL injury on his Bundesliga debut. Now Karetsas, the other pillar of that recruitment drive, is undergoing hospital tests after collapsing in his very first Champions League outing.
For Niko Kovac, the tactical puzzle grows more complicated by the week. The schedule is tightening across league and Europe, and the two marquee summer signings around whom so much of the project was built are suddenly unavailable or uncertain. This is not the version of Dortmund he thought he would be coaching in September.
Guirassy steps up as game erupts
On the pitch, the game had been stuck at 0-0 when Karetsas left, the football overshadowed by anxiety and concern. For a while, it felt secondary, almost irrelevant.
Then the match snapped back into focus.
The contest opened up, chances finally flowed, and what had been a tense, subdued affair turned into a wild Champions League tie. Dortmund found a way to harness their emotions, to channel the worry into something more aggressive, more determined.
Serhou Guirassy, on his 100th appearance for the club, seized the moment. The forward struck a late brace, dragging Dortmund over the line in a 3-2 win and pushing his goal tally past that of Robert Lewandowski at the same milestone. In any other context, that statistic would dominate the headlines.
Not this time.
The victory keeps Dortmund’s European campaign firmly on track, the three points in Spain potentially crucial in a tight group. Yet as the players left the pitch, their thoughts were already elsewhere.
The night will be remembered less for Guirassy’s landmark and more for a teenager’s interrupted debut, a club holding its breath, and the uneasy question hanging over Dortmund’s season: how many more blows can this ambitious project absorb?
