Billy Gilmour and Scott McTominay played together for Scotland in a UEFA Nations League Group A1 game against Croatia on Saturday.
The Scots took the lead in Zagreb through Ryan Christie but Igor Matanovic levelled within minutes for the hosts.
Andrej Kramaric then scored what proved to be the winner although Scotland had a last-minute equaliser ruled out by VAR.
The Napoli duo both played the entire match.
