Teun Koopmeiners

AZ

Koopmeiners grew up in Castricum, North Holland, and took his first steps in football as a youth player for the local club, Vitesse '22. In 2009, he joined the AZ youth academy at under-12 level. He eventually progressed through the ranks, and as part of the club's reserve team, Jong AZ, he became champion of the Dutch third division in the 2016–17 season, reaching promotion to the Eerste Divisie.

On 18 August 2017, Koopmeiners made his professional debut for Jong AZ in a 3–1 away win over FC Den Bosch. He made his first team-debut on 1 October, coming on as a substitute for Alireza Jahanbakhsh for the final 30 minutes of a 4–0 home loss to Feyenoord. At the end of the 2017–18 season, AZ ended in third place, and thereby qualified for Europa League. In his first professional season, he made 26 league appearances in which he scored one goal.

On 1 March 2020, Koopmeiners played a 70-metre pass to set up Oussama Idrissi for AZ's second goal in a 2–0 win against Ajax which put his side level on points with Ajax. During the 2019–20 AZ Alkmaar season Koopmeiners scored 16 goals in all competitions in 42 appearances, helping his side finish second in the Eredivisie on goal difference behind the Champions AFC Ajax.

He scored his first goal of the 2020–21 season against Viktoria Plzen on 26 August 2020 in the UEFA Champions League qualifier 3–1 victory. On 14 January 2021, Koopmeiners scored two goals, including an audacious backheel flick, to help his side clinch an 3–1 away victory against PSV Eindhoven.
