The Sampdoria defender only made his international debut last week but has been selected along with the likes of Marek Hamsik and Martin Skrtel ahead of the tournament
Sampdoria defender Milan Skriniar has been included in Slovakia's 23-man squad for Euro 2016, despite only making his international debut last week.
The 21-year-old featured in back-to-back 3-1 successes as Jan Kozak's side beat Georgia and world champions Germany in pre-tournament warm-ups, and played well enough to earn a spot in the final group.
Skriniar now joins more established names Martin Skrtel, Marek Hamsik and Juraj Kucka in a selection that includes just two forwards.
