Kenny McLean scored his first goal for Scotland on Sunday evening in an important UEFA EURO 2020 qualifying victory over San Marino.
After the disappointment of the defeat to Kazakhstan in their opening game of Group I, Scotland boss Alex McLeish made a number of changes to his starting line-up, including bringing in McLean for his sixth cap.
And the City midfielder repaid the faith shown in him by expertly heading home Ryan Fraser's cross inside four minutes.
The Scots had to be patient against the European minnows but sealed the three points with 15 minutes left on the clock after Johnny Russell's emphatic strike.
Like McLean, City youngster Adam Idah (pictured) got his name on the scoresheet as he made his debut for the Republic of Ireland Under-21s on Sunday.
Prolific at Under-17 and Under-19 level, Idah continued his hot streak for the Boys In Green, netting twice in their 2021 UEFA European Under-21 Championship qualifying campaign victory over Luxembourg.
Jamal Lewis also enjoyed a winning weekend with his national team. After helping Northern Ireland to victory over Estonia on Thursday, the City left-back once again played 90 minutes in another qualifying triumph for Michael O'Neill's men.
The 2-1 win over Belarus on Sunday evening saw them leap to the top of Group C, ahead of Germany and the Netherlands.
Elsewhere, Teemu Pukki and Finland will be looking to get their first points of their qualifying campaign when they take on Armenia on Tuesday evening.
Finland lost 2-0 to Italy on their opening game of Group J on Saturday night, with Pukki playing 83 minutes.
Timm Klose's Switzerland are back in action on Tuesday as well, looking to build on their victory over Georgia on Saturday. They face Denmark at home, with Klose aiming to feature after being an unused substitute at the weekend.
Back to youth level, England Under-19s face an uphill task to reach the finals of the 2019 UEFA European Under-19 Championship this summer.
Defeat in their second Elite Round game against Greece on Saturday means qualification is out of their hands. They require victory in their final qualifier against Denmark on Tuesday and hope group leaders Greece drop points in their last game.
Max Aarons featured as a second-half substitute in the Greece defeat and will hope to be recalled to the starting eleven by Head Coach Keith Downing after playing the full 90 minutes in their opening qualifying win over Czech Republic.
Elsewhere, Ben Godfrey (pictured) will hope continue on from the 90 minutes he clocked for England Under-20s on Thursday in their defeat to Poland. The Young Lions will face Portugal on Tuesday.
As for Monday's action, Andrew Omobamidele and Josh Giurgi could feature in Republic of Ireland Under-17s friendly with Finland.
