Paddy McNair and George Saville both started for Northern Ireland, whose unbeaten run in Euro 2020 qualifying came to an end last night at the hands of Germany.
Michael O'Neill's side had won all four of their opening qualifying fixtures to take them top of Group C, but they were undone by Germany last night at Windsor Park.
A volley from Marcel Halstenberg early on in the second half put the visitors in front and with 20 minutes to go, Saville made way for Hull City striker Josh Magennis.
However Serge Gnabry scored Germany's second in stoppage time to seal the win for the three-time European champions and snap Northern Ireland's unbeaten run in their qualifying campaign.
Marcus Tavernier was in from the start for England's Under-20s, who scored deep into second half injury time to defeat Switzerland.
Leeds United's Jack Clarke netted the decisive goal for the Young Lions.
Elsewhere, Nathan Wood featured for England U18s twice in the space of two days, with the Young Lions narrowly defeating Australia 3-2 on Friday night and were held in a 1-1 draw against Brazil on Sunday.
Darren Randolph and the Republic of Ireland are back into action this evening with a friendly at home to Bulgaria (7.45pm).
After helping Scotland U21s get their Euro U21 qualifying campaign off to a strong start, Paddy Reading could be involved again tonight as they prepare to face Croatia (8pm).
