Borussia Dortmund signs the transfer sensation of the summer: Giannis Konstantelias signs a five-year contract in Dortmund. The 23-year-old Greek was a creative leader and a fan favorite at PAOK Saloniki. Experience in a highly emotional club, Konstantelias has gathered enough. ## What happens? The Greek has the abilities of a classic 'number ten'. Fine dribbling. Calmness on the ball. Overview for his teammates. 'The little wizard', they called him affectionately in Greece. But so talented Konstantelias is, after a one-to-one replacement for the El-Mala deal that fell through, it doesn't sound like that. ## Why it matters for Borussia Dortmund The Greek is an important new arrival for the Dortmund offense. With his playing style, he is similar to his fellow Greek Konstantinos Karetsas. ## What comes next? It remains to be seen what roles Kovac has in store for Konstantelias and Karetsas. In order for one of the two to switch to the wings, a different tactical basic formation would be needed. Currently, there is no space on the outside for a three- or five-man chain with offensive wing players. Currently, Borussia Dortmund is in second place in the Bundesliga, with 70 goals this season and 34 conceded (+36 goal difference). The title holder Bayern Munich is 16 points ahead. The next game is on September 12, 2026 against SC Paderborn 07.
