Steven Davis was the star of the night as Southampton's players rounded off the international week on Tuesday.
Saints' club captain skippered Northern Ireland to a 3-0 home friendly win over Israel, setting his country on the way to victory with a superb 12th-minute goal.
Davis's beautiful first-time effort from 18 yards, which came from Paddy McNair's clever corner, thundered past Guy Haimov in the Israel goal to the delight of the Windsor Park crowd.
Further goals from Stuart Dallas and Gavin Whyte sealed the resounding win, as Michael O'Neill's team bounced back from last week's loss to Bosnia & Herzegovina in their opening UEFA Nations League match.
Elsewhere, Saints keeper Alex McCarthy saw his wait for a senior England cap go on.
McCarthy would have been hoping to see some action in the friendly with Switzerland, at Leicester City's King Power Stadium, but Jack Butland was given the nod ahead of him, with the Saints stopper forced to watch from the bench for the duration.
England edged the game 1-0, with Marcus Rashford netting early in the second half.
Another Saints player to start on the bench was Jan Bednarek, as Poland hosted Republic of Ireland in a friendly.
The centre-back, who started last week's Nations League draw away to Italy, was introduced just after the hour mark, with Poland trailing to an Aiden O'Brien goal.
They ended the night with a 1-1 draw, though, as Mateusz Klich netted with three minutes left on the clock.
Earlier in the day, goalkeeper Angus Gunn was an unused substitute as England Under-21s triumphed 2-1 away to Latvia in a EURO 2019 qualifier.
Goals from Tammy Abraham and Mason Mount mean the Young Lions are now within touching distance of sealing a place in next summer's finals.
