Arsenal boss Arsene Wenger says his young players will learn from their defeat to Olympiakos.

Despite the disappointment of the defeat, Wenger feels the trip to Greece and the intimidating Georgios Karaiskakis Stadium will have stood the likes of Emmanuel Frimpong, Francois Coquelin and England Under-21 international Alex Oxlade-Chamberlain in good stead.

"It was a fantastic experience they realise what intensity that you need at this level and some young players have shown good things," said Wenger.

"But there was a bit of lack of experience and maturity in midfield where you need to hold the ball better when we were under pressure."
