Senior caps Declan John and Harry Wilson have been included in the Wales Under-21 squad for the UEFA Under-21 Championship qualifier against Denmark.
Geraint Williams' side are top of Group 5 following wins over Bulgaria and Luxembourg.
They face a sterner test against top seeds Denmark in Aalborg on Friday, 9 October.
"It's a great test for us and a great opportunity at the same time," Williams said.
"They're top seeds for a reason and are very organised.
"It's been a good start and we've scored six goals in our first two qualifying games so far."
