Fulham's Luke Harris has been called into the Wales squad for the Nations League games against Belgium on 22 September and Poland three days later.
The 17-year-old attacking midfielder has only made one senior appearance for Fulham, in the EFL Cup this season.
But Harris has caught the eye of Wales manager Rob Page, who signed a new four-year contract this week.
Although Harris' experience at senior level is limited, his record at age-group level is impressive.
The Jersey-born player debuted for Fulham Under-18s as a 15-year-old and last season established himself in the Premier League club's under-23s, scoring 13 goals in 17 league appearances.
"He (Harris) has been in the system now for a few years. He's a talent and an exciting prospect, he's doing really well at his club and he scores goals," Page said.
"When you have someone with that talent - albeit that he's just turned 17 years old - then I am not bothered about his age.
"I have shown that in the past with Rabbi (Matondo) and Joe Rodon and DJ (Dan James) and others I have worked with at under-21 level and the younger age groups.
"If I think they are good enough, they will come in and be part of the environment.
"For these two games, I think it's a great opportunity for him to come in and get a taste of it, to experience it, and for us to have a look at him. We can see what we have seen at club level."
Although Page says his squad for November's World Cup is almost set, he admits there are still opportunities for less-established players - including Harris - to earn a place on the plane to Qatar.
"I never say never - absolutely. I have pretty much got the squad in mind, of course. But the door is never closed. If someone is doing really well and I think it's going to benefit us, then he will be considered," he added.
