Donley, on-loan with Stoke City, struck from the spot as Northern Ireland won 1-0.
The youngster admits he's been modeling part of his game on former Spurs teammate Harry Kane.
“That’s probably why I like to try and drop deep because I’m trying to do what he does,” Donley said of Kane.
“He helped me a lot when he was around just with different types of advice and stuff. So, yes, it’s good to learn from the best.”
On Northern Ireland coach Michael O'Neill's instructions, Donley added: “Michael always speaks to me about playing me as a striker.
“He can see me playing there, and he kind of just said to take my opportunity. Luckily, I scored. Normally, I’m behind the striker but with this, it’s more about running behind more and stretching the game. I can add that to my game, definitely.”
