Borussia Dortmund signs Greek talent Konstantinos Karetsas

On August 3, 2026, Borussia Dortmund officially announced the signing of 18-year-old Greek attacking midfielder Konstantinos Karetsas. The player, who joins from the Belgian club Genk, has signed a five-year contract that keeps him with the German side until June 30, 2031. The transfer fee is estimated at 35 million euros, with potential performance-related bonuses that could push the total value beyond 40 million euros, marking the most expensive sale in the history of the Belgian club.

The club marked the signing with a creative promotional video filmed at a local souvlaki shop in Kamen, Germany. Karetsas, who will wear the number 19 jersey, expressed pride in joining the club and stated his commitment to achieving future successes with the team. A public presentation for the player was scheduled for 16:00 Cyprus time at the Olympia Grill in Kamen, rather than the team's home stadium.

Karetsas has been recognized as a standout talent in the Belgian league over the past two years, attracting the interest of the German giants. This acquisition represents a significant long-term investment for Dortmund as they seek to strengthen their squad for the upcoming seasons.
