Lubo Satka made his debut for Slovakia under-21s in Saturday's friendly against England's 'C' team.
The 18-year-old defender received an emergency call-up to the squad, having been named by coach Ivan Galad as first reserve, and was named on the bench in Poprad.
In the 92nd minute, he entered the fray as his side won 1-0.
Ilava-born Satka, who has already played for his country at under-17, under-18 and under-19 level, will now join up with the Slovakia under-20s squad ahead of their game against Estonia on Tuesday, 27th May.
