Exeter City manager Paul Tisdale has noted that Ghanaian born Ethan Ampadu is joining the Wales Squad for their World Cup qualifier because school is not in session.
Ampadu, 16, who is sitting his GCSE exams, has been included in the squad for the training camp in Portugal.
"He's not missing any school but his priority at the moment is his exams," Tisdale said.
"He probably couldn't go away with Wales unless it happened to coincide with half-term week, which it does."
Ampadu has represented Wales up to Under-19 level, but is also eligible for England, the Republic of Ireland and Ghana.
Tisdale described the defensive player as a "remarkably gifted but grounded young man".
The Exeter-born teenager made his professional debut for the Grecians in August 2016 and was named Wales' young player of the year in November.
