Pierre-Emerick Aubameyang has warned Arsenal's youngsters to prove themselves when their chance arrives.

William Saliba and Matteo Guendouzi, on-loan from Hertha Berlin, have both expressed frustration over their playing chances at Arsenal.

"When you are a young player trying to come through at a club like Arsenal then for sure there's a lot of pressure," Aubameyang told AFP.

"You have to be patient too because we have great players who are playing in the first team so it's always hard to find your way through.

"I remember when I was playing at AC Milan (2008-11) it was always really, really difficult to get into the first team, so I know that type of feeling."

Aubameyang is in no two minds about where the best place is for these academy stars to learn their trade and bide their time.

"With the Europa League this season, there have been maybe more opportunities for the young guys to get minutes," he said. "We saw a few young players in our last European game and we also have them joining in with training quite a lot lately.

"For them it is not easy, but when you get the chance you have to take it and I think they are doing well when they have had the chance so far.

"You can see that the young lads always perform when they come in because the coaches are doing great work with them to get them ready for the games.

"The rest is down to them."
