Borussia Dortmund's Konstantinos Karetsas Hospitalised After Collapsing in Champions League Debut

During Borussia Dortmund's Champions League match against Villarreal, teenage talent Konstantinos Karetsas collapsed on the pitch, prompting an urgent medical response. The 18-year-old forward was making his first appearance in Europe's top competition when he suddenly struggled, signaling distress before sitting down on the grass.

Medical Emergency Unfolds

The incident shocked fans and players alike as Karetsas appeared to have circulatory issues during the game. After a routine pass, he showed signs of discomfort and had to be helped off. He was immediately taken to hospital for further examination.

Dortmund's Official Statement

The club confirmed that Karetsas left the field due to circulatory problems. They reported that he was stable and undergoing additional tests. Goalkeeper Gregor Kobel shared his hope for a swift recovery, telling Amazon Prime, "I hope and I think that everything is OK and I hope that he’s back and fit with us soon."

Summer Signings and Setbacks

Karetsas joined Dortmund in the summer alongside fellow Greek international Giannis Konstantelias. The club invested heavily, paying around €30 million for Karetsas from Genk, while Konstantelias arrived from PAOK for €26 million. Both were expected to play key roles this season.

Unfortunately, injuries have hit Dortmund's new signings hard. Konstantelias suffered a severe ACL injury on his Bundesliga debut, likely sidelining him for the rest of the season. These setbacks pose tactical challenges for manager Niko Kovac as domestic and European fixtures pile up.

Dortmund Secures Victory Amidst Concern

Despite the unsettling atmosphere after Karetsas’ collapse, Dortmund rallied to win 3-2 in Spain. The score was still 0-0 when the youngster left the pitch, but the game eventually burst into action.

Guirassy, marking his 100th appearance for the club, scored twice late on, securing all three points and surpassing Robert Lewandowski's goal tally. While the win keeps Dortmund's Champions League hopes alive, the main focus remains on Karetsas' health and recovery.
