Amsterdam - Uncapped teenage defenders Jairo Riedewald and Kenny Tete were both in a preliminary squad of 31 named by the Netherlands for next month's Euro 2016 qualifiers against Iceland and Turkey.
New coach Danny Blind's first selection also sees a return for Newcastle United's Vurnon Anita, who won the last of his two caps for the Netherlands five years ago.

Riedewald (18) and Tete (19) began the new season for Ajax as first-choice centre backs for the first time. Tete played his debut game for Ajax only in February.
The Dutch host Iceland on Sept. 3 and meet Turkey away in Konya three days later. Blind has taken over from Guus Hiddink, who resigned at the end of June with the Dutch sitting third in their qualifying group.
The Netherlands, who will trim their squad next Friday, are five points behind leaders Iceland and three behind second-placed Czech Republic in Group A.
