Much has been made of Jurgen Klopp's 'Liverpool reloaded', now Michael O'Neill is attempting something similar with his Northern Ireland 2.0.
The average age of his team was just 23.5, with an average of 14.5 caps across the eleven players who started in Bucharest.
It's a complete contrast to the team he guided to the Euro 2016 finals, which was a side with international experience right through its backbone.
His new Northern Ireland team are anything but that. The oldest player in his starting team was Jamie Reid at 29, who was making his debut.
Paddy McNair and Jordan Thompson are experienced heads, but the only other players to have double figures in caps were 20-year-olds Conor Bradley and Shea Charles on 13 caps, while 22-year-old Trai Hume had 10.
