The Newcastle United youngster scored the winner as Neil Dewsnip’s men defeated Poland 3-2 on Saturday in the first of a double header between the nations.

That strike took his total to 16 in 21 games for England, and although he admits his target is a goal-a-game ratio, he says that he is just pleased to be contributing to a winning team.
"I think it’s quite good," he told TheFA.com. "The target is to score every match, and if you can score one a game then that’s a bonus but it’s also important to create chances for your team.
"Luckily I’ve been able to score quite a few goals while I’ve been away with England to go with those I’ve scored at Newcastle as well, so it’s been good."
He added: "I’ve got a few now, but my favourite goal with England was this time last year in the European Championship qualifiers for the U17s against Gibraltar. I just smashed it from 35 yards and it flew into the top corner."
Armstrong and his team-mates suffered a frustrating time during the first half of Saturday’s encounter as they failed to turn their dominance into goals and found themselves trailing at the break, but the response from the Young Lions in the second half left the hotshot pleased.
"It was great," he added. "We obviously knew coming out to Poland it was going to be tough. But the lads done really well and I’m happy myself that I could get another goal and we got the win.
"It was a bit frustrating during the first half, but that’s what happens usually for strikers. Not every chance you can score, and that’s what it was like first half and we came in getting beat.
Tough battle v Poland today but glad to win 3-2! Always nice to get a goal for your country aswell! ⚽️👍

"But we came out fighting and got the goals back, and luckily I got one as well.
"You could feel the momentum changing. Everyone is pushing forward and we were getting more and more chances, and we took them. The lads were excellent second half."
Armstrong recently suffered the loss of his granddad, and he was extra pleased that he could find the net in his memory.
"My grandad used to be a footballer when he was younger at Hartlepool United, and that was for him," he explained.
Having added to his scoring record, he is looking to for a similar outcome on Monday afternoon in Gdansk.
"It has to be the target. We will know what each other are good at and it’s going to be another tough game - but I think we’ll get the victory if everyone performs."
Having made his first-team debut in the Premier League last season for the Magpies, Armstrong has gone on to make several more appearances for Alan Pardew's side this campaign, however, it has been in the cups where he has had the most impact.

Armstrong's England record
He produced a fine display as he claimed two assists to help his side defeat Crystal Palace 3-2 in the League Cup, securing a spot in the next round against Manchester City last month.
Pardew handed Armstrong his chance again at the Etihad, and although he admits to feeling a few butterflies beforehand, the Newcastle-born youngster gave another mature display as his side defeated the reigning Premier League champions 2-0 on their own patch.
"It was hard, before the game I didn’t really know I was starting until the day so I was nervous to be honest," he admitted.
"To play against experienced international centre-halves [Martín Demichelis and Eliaquim Mangala] like that was amazing for me and my development.
"And having played against them, I have the confidence to play against anyone with no fear. That’s the way I see it."
And with a quarter final coming up next month against Tottenham Hotspur, Armstrong is allowing himself to dream with being only two games away from a possible Wembley appearance.
"It’d be class," he added. "The club hasn’t been to Wembley in my lifetime, so for me to be a part of the squad that’s fighting to get there is fantastic – we’d love to do it for the fans."
