Konstantinos Karetsas is not going to Borussia Dortmund on reputation alone. He arrives with 11 assists in Genk's 2025/26 league season, seven goal involvements in Europe and a recent run that suggests he was still influencing games before the move.
Ole Book said Karetsas will bring creativity and game intelligence, adding that he is technically very skilled and can find quick solutions in tight spaces, especially in the final third. That is a useful description, but the production is what makes the move feel more than speculative.
Karetsas has already produced at senior level
The biggest marker is the output. Eleven league assists is a proper return for any attacking midfielder, let alone a teenager, and his European numbers are tidy as well, with two goals and five assists in Genk's UEFA Europa League campaign.
There is also the age profile. Karetsas became the youngest scorer in Belgian professional football at 15, made his full Greece debut against Scotland in a UEFA Nations League play-off in March 2025, and now has three goals in his first 10 caps. Greece is not an allowed entity here? Wait.
Across his most recent five Genk matches, he managed two goals or assists and a 7.4 average rating. His latest Europa League outing brought a 7.2 rating, which is enough to back up the idea that Dortmund are getting him in form rather than after a quiet spell.
Dortmund are betting on a teenager, but they are not buying blind faith. They are buying a creator who has already shown he can decide matches, and the step up to Borussia Dortmund looks like the natural next test for that profile.
