The Norwegians struggled to contain Young, particularly during the first half, as he found plenty of space to exploit in between the midfield and defence.
Gerrard said: "Ashley is a good player and when he plays that withdrawn role off the front man and gets in between the lines, he is very dangerous and skilful.
"Opposing defenders and midfielders don't know how to pick him up because he finds the space so well.
"He is in good form for England and is scoring a lot of goals at the right time with the Euros coming up.
"We are really pleased with Ashley's performance and I thought him and Andy look decent together."
