"It's a harder trick to pull off buying younger players," he said Wenger. "But I am not too much worried about the competition because [the players] will always go where they think they get the chance.
"Not many clubs have the patience to give them a go. They will make them wait until they think they are good enough.
"Here, a player knows if he is good he will play and because we start them early here, they mature earlier.
"Players are integrated into our training sessions early so they know exactly what they have to do."
