Wales boss Chris Coleman is confident Chelsea youngster Ethan Ampadu will remain committed to the nation after making his senior debut in Friday's 2-0 friendly defeat to France.
Exeter-born Ampadu was capped by Wales at under-17 and U19 level before being promoted into the senior squad, and he was sent on just after the hour mark in Paris.
His first full Wales cap has come just 57 days past his 17th birthday, but the fact that it was a friendly means he is still eligible to play for England, Ghana and Republic of Ireland.
Sheffield United's 20-year-old midfielder David Brooks, who made his senior debut alongside Ampadu, also remains eligible to play for England.
"They're not legally bound to us," Coleman said. "We spoke some years ago to the younger players and their parents and explained the pathways.
"That's all we can say and there's nothing we can do if any player changes their mind. I've worked and spent time with the players we've got.
"In football you shouldn't be surprised by anything but I'd be amazed if they left us. The players are firmly committed to us."
Ampadu has already made his Chelsea debut this season and is capable of playing in midfield or in central defence.
"Ethan's capable of playing both," Coleman said after utilising Ampadu in a midfield role at the Stade de France. "His frame, athleticism and understanding of the game ... he's a great communicator for someone so young.
"So at the moment it [best position] is a tough one to call. He could end up playing holding midfielder or as a centre-back.
"He's got a long way to go before you can liken him to someone like Rio Ferdinand, but I remember him coming on at West Ham in midfield.
"But he gravitated into a centre-back, probably the best the Premier League has seen in the last 20 years.
"You never know what's going to happen in the future, but Ethan is definitely capable of playing both positions.
"The modern day centre-back starts play and has to be confident in possession and Ethan can do that."
