Peer Koopmeiners

Peer Koopmeiners is a Dutch footballer who plays as a midfielder for AZ Alkmaar, of which he is captain. He was born in Castricum, near Alkmaar, and is the younger brother of Teun Koopmeiners, a Juventus midfielder.

Career

Peer grew up, together with his brother Teun, in the AZ Alkmaar youth academy. The two brothers' paths diverged in 2021, when Teun left the Netherlands to move to Italy, to Atalanta: Peer instead stayed in Alkmaar, where he completed his progress through the youth ranks up to his first-team debut, later becoming captain of the Dutch side [2].

The match against his brother in the Europa League

On 5 November 2026, AZ Alkmaar faced Juventus in the Netherlands in the fourth round of the Europa League league phase. The match pitted the two Koopmeiners brothers against each other for the first time in an official fixture, after a previous youth friendly. Peer led AZ Alkmaar as captain, while Teun started from the first minute wearing the Juventus shirt [2]. For the occasion, the home fans displayed a banner reading "Two brothers, one love", accompanied by a picture of the two of them as children [1]. Before the match Peer had said: "It will be special to face a brother in the Europa League, for the family and probably for Teun himself too. I know what he means to the club and the fans and how much he has given. I'm proud of my brother, I respect him" [2].

The book with his brother

Teun and Peer Koopmeiners wrote a children's book together, with the patronage of the municipality of Castricum, titled «De voetbalbroers, voetballen als een prof» ("The footballer brothers, playing football like a pro"), dedicated to their childhood in the Netherlands and the path that led them to European football [2].
