Core Event
During Dortmund’s Champions League group-stage match against Villarreal, 18-year-old Greek midfielder Konstantinos Karetsas collapsed on the pitch without any contact from an opponent. After signalling distress to the referee, he was treated on the field, then stretchered off and taken to a nearby hospital for further examinations. Dortmund’s medical staff described the incident as a “circulation problem.” The match continued, and Dortmund ultimately secured a 3-2 victory.
Background & Context
Karetsas arrived at Borussia Dortmund in the summer from Belgian side Genk for a reported €30 million transfer. He joined fellow Greek international Giannis Konstantelias, who was signed for €26 million from PAOK. Konstantelias suffered an anterior cruciate ligament tear on his Bundesliga debut, representing a significant injury setback for the club. Despite these challenges, Dortmund began the season with two Bundesliga wins and entered the Champions League campaign seeking to build momentum.
