International round-up: Flekken makes Netherlands start
Brian Brobbey put the Netherlands ahead in the first half, but Ermedin Demirović equalised after the break as the spoils were shared.
Flekken’s fellow keeper Hákon Valdimarsson was also in action on Tuesday, with his Iceland side closing out their Nations League campaign with a 4-1 loss at Wales.
Andri Guðjohnsen opened the scoring before Craig Bellamy’s side turned the game around in Cardiff.
Valdimarsson now has 17 senior Iceland caps to his name, having played 13 successive games across all competitions dating back to November 2023.
Yunus Emre Konak captained Turkey U21 for the first time in their friendly defeat against Serbia.
After leading the side out, the Bees midfielder played 90 minutes in the 2-1 defeat.
Returning to the Nations League, Yehor Yarmoliuk was an unused substitute for Ukraine as they won 2-1 away from home against Albania.
Yarmoliuk was involved in the senior squad for the first time over the last week.
Elsewhere, Jayden Meghoma was also an unused substitute for England, who ended their European Under-19 Championship qualification with a goalless draw against Belgium.
That point ensured the Young Lions made it through to the elite qualifying round next spring.
The left-back previously started in narrow wins against Bulgaria and Lithuania during this international window.
Finally, Marley Tavaziva was on the bench for Zimbabwe in their 2-1 defeat to Cameroon in Africa Cup of Nations qualification.
