Arsenal boss Arsene Wenger was delighted with the character his young team is showing in recent games.
After victory over Newcastle, he said: "We are a very, very young side. The spirit is great, the quality is there and we feel we are going forward from game to game.
"People don't realise how young we are in the Premier league and what we do.
"Today, you had six or seven players between 20 and 22 on the pitch."
