Dennis van der Heijden

ADO Den Haag

Van der Heijden made his debut for ADO Den Haag on 14 February 2016 against Excelsior. He was brought on as substitute for Vito Wormgoor in the 77th minute, with Den Haag trailing 2–1, and scored twice to help the club complete a 4–2 come-from-behind victory. In doing so he became the first player to net a brace for the club on debut since Dmitri Bulykin in 2010. On 24 March, van der Heijden signed his first professional contract, signing a three-and-a-half-year deal. He ended the season with nine appearances and two goals to his name as The Hague finished 11th in the Eredivisie. On 17 June, van der Heijden was named runner-up for ADO Den Haag's Goal of the Season award for his goal against Excelsior, losing out by 4% to club goalkeeper Martin Hansen.

Loan to Volendam

Van Der Heijden scored his first goal of the season on his KNVB Cup debut in a 2–1 win over Telstar on 25 October 2016, coming off the bench to score the winner in the 81st minute of the match. He failed to score in 16 Eredivisie appearances by January though, and at the end of the month was loaned to Eerste Divisie side Volendam. He made his debut for the club on 3 February 2017, starting in a 3–1 loss to Emmen and scored his first goal ten days later, netting Volendam's opener in a 4–2 win over Utrecht II. He ultimately made 9 appearances for the season and scored 3 goals as Volendam were defeated in the promotion play-offs by NAC Breda.

Following his breakthrough with ADO Den Haag earlier in the preceding league campaign, van der Heijden was named in Aron Winter's side for the U19 European Championship. He made his debut for the Netherlands U19 side in their opening match of the tournament on 12 July, coming on as a late substitute for Steven Bergwijn in a 3–1 win over Croatia. He scored his first goal for the U19's in Netherlands' final match at the tournament, which ultimately ended in a penalty-shootout loss against Germany which saw them fail to qualify for the 2017 FIFA U-20 World Cup. On 7 October 2016, van der Heijden scored four goals for Netherlands U20 in a 5–3 win over the United States in a Four Nations Tournament.
