Arsenal boss Mikel Arteta was delighted with their Europa League victory at Molde.
The Gunners won 3-0 via goals from Nicolas Pepe, Reiss Nelson and Folarin Balogun.
Arteta was pleased with his young players, declaring: "We decided to give them chances because you have to give them real opportunities. For me to play them in friendly games is not a real chance. Youn have to give them the right competition and you have to surround them with senior players and big players around them.
"Then you can assess whether they're at the level, whether they have the personality to play at this club, how they react to good and bad moments and this is what we are trying to do. To play the next game, they have to earn it, just like everybody else in the squad, because we want to finish first. I think we are using our young players well in the competition."
Arteta was happy with the three goals scored on the night.
"This is what we want [to do]. We've been more efficient in this competition. It can be down to some of the players that we utilise in certain positions, it can be because of the opposition, there are a few factors there.
"I must say that if we want to be fighting with the big clubs, obviously the amount of goals that we score has to improve because defensively I think we've had four clean sheets in the last six games, which is pretty good, but offensively our numbers have to improve."
