Armstrong has just capped off an impressive 12 months by helping fire Blackburn back to the Championship after lifting the Under-20s World Cup last summer.
Now he is desperate to add another trophy to his collection with U21s at the Toulon Tournament.
Armstrong, who also won the U17s Euros with the Young Lions in 2014, told The Sun: “You never get tired of winning trophies for your country.
“We know that England have won this the last two years and it's up to us to come here and do the job again.
“It's a big tournament that everybody wants to win and hopefully we can get over the line again."
He added: “It's always a striker's aim to get amongst the goals and if I can do that out here then that can only be a good thing for me.
“Last season was a massive learning curve for me. I'm still only 21 and it's all about learning but I've played over 100 league games now.
“That's the main thing to keep getting experience, getting as many games as I can and pushing on."
