The Newcastle United youngster, on loan at Coventry City, celebrated another win. This time at international level.
The Young Lions had to contend with an astonishingly bad playing surface but still came away with the victory, with Armstrong both taking part and celebrating the victory on Twitter after the game.
The result marks the continuation of a very promising season indeed for the 18-year-old, who has enjoyed a stellar campaign so far on loan at Coventry City.
And the teenager was also able to celebrate another Coventry win while he was on international duty, with Tony Mowbray's team fifth in League One.
While Armstrong flourishes, of course, Newcastle have been toiling. Despite that, many appear to be against the 18-year-old being recalled to the Magpies, as it would likely stunt his development.
Armstrong wouldn't be guaranteed game time at St James' Park and, frankly, such is the mess Newcastle find themselves in, the teenage striker will be learning far more in the Football League.
As for England, another win for the young side, with the Newcastle youngster once again playing his part for his country.
