Taty Castellanos and Argentina U-23s have secured their place at the 2020 Tokyo Olympics.
The Albiceleste became the first South American team to punch their ticket, becoming continental champions following the CONMEBOL pre-Olympic qualifying tournament.
Valentin started once and made five substitute appearances for his nation, helping them to a 6-1-0 record in the competition which was enough to see them crowned champions.
Only a defeat to Brazil in their final match spoiled an otherwise perfect record, meaning Argentina will go for a third gold medal in Tokyo in the U-23 tournament.
Jesus Medina also suited up for Paraguay in the qualifying tournament but defeats to Uruguay, Peru and Brazil ended their hopes of reaching the finals.
