Dortmund's Champions League Win Overshadowed by Karetsas Collapse
Dortmund’s Champions League win in Spain was supposed to be a launchpad for a new era of young talent. Instead, it turned into a night of alarm and uneasy silence.
Shock in Spain as Karetsas Collapses
Midway through his Champions League debut against Villarreal, 18-year-old Konstantinos Karetsas played what looked like the most ordinary of passes. No heavy challenge. No dramatic collision. Just a simple ball to a teammate.
Seconds later, he was in clear trouble.
The midfielder slowed, signalled urgently to the referee, then lowered himself to the turf as players from both sides waved for medical staff. The stadium noise dipped, replaced by a tense murmur as it became obvious this was no routine injury.
Dortmund later confirmed that Karetsas had suffered circulatory problems.
“Konstantinos Karetsas had to leave the field due to circulatory problems,” the club said in a statement. “Kosta is doing well under the circumstances and is on his way to the hospital for further tests.”
It offered some reassurance, but not enough to ease the concern that swept through the squad.
Dressing Room on Edge
Speaking after the 3-2 win, goalkeeper Gregor Kobel gave voice to what everyone around Dortmund was feeling.
“I hope and I think that everything is OK and I hope that he's back and fit with us soon,” he told broadcaster Amazon Prime.
No dramatics, just a teammate hoping the teenager who had just seen his big European night cut short would be back in the dressing room sooner rather than later.
Karetsas’ collapse came at 0-0, in a game that had not yet found any rhythm. The football, for a while, stopped mattering.
A Costly Summer Under Strain
Karetsas arrived at Signal Iduna Park in the summer as one of the headline signings in a bold youth-focused rebuild. Dortmund paid around €30 million (£25.7m/$34.9m) to bring the former Belgium youth international from Genk, underlining how central he was to their long-term plans.
He was not alone. Fellow Greece international Giannis Konstantelias joined in the same window from PAOK for €26m (£22.3m/$30.2m). Two blue-chip prospects, two pillars of a new Dortmund, both expected to shape the club’s European campaign.
The plan has been shredded by misfortune.
Konstantelias’ season was effectively ended last month when he suffered a serious ACL injury on his Bundesliga debut. Now Karetsas, the other marquee arrival, is undergoing hospital tests after a worrying on-pitch collapse.
For Niko Kovac, the tactical puzzle has turned into a full-blown headache. The schedule is tightening across league and Europe, and the players earmarked to refresh his side are either sidelined long term or facing immediate medical uncertainty.
Guirassy Delivers on a Night of Unease
Once play resumed in Spain, Dortmund had to somehow reset. It was never going to be just another group-stage game after that.
The match, goalless when Karetsas left the field, eventually broke open. Chances came, mistakes followed, and the tempo spiked. Villarreal pushed. Dortmund punched back.
On his 100th appearance for the club, Serhou Guirassy seized the stage.
The forward struck twice late on, a ruthless brace that dragged Dortmund over the line and secured a 3-2 victory. In doing so, he moved past Robert Lewandowski’s tally, a landmark that underlined his importance on a night when others were missing.
Those goals keep Dortmund firmly in the hunt in the Champions League. The result matters. The table matters.
But as the team left Spain, three points in the bag and the group campaign on track, one question cut through everything else: how quickly will Karetsas be back, and what will this mean for a Dortmund season already walking a tightrope between promise and bad luck?
