Wenger was asked if he had United's past success with kids in mind as he planned for Arsenal's future.
Wenger said: "Yes, of course, it's important. The sense of belonging is important and it has been neglected in the modern game.
"It is important for the players to feel part of the culture of the club, that the club means something to you. It is important for the fans as well.
"I believe in difficult times that feeling of belonging is very important and that can only be linked to players growing up together.
"For example, we have Wojciech Szczesny in the Arsenal team. For me he is an Arsenal player. Why? Because he grew here and at 15 years of age he was here. Like Wilshere, he came here at 10 years of age. There is something more there that you can build on.
"United had an exceptional group together. The two Nevilles, Beckham, Giggs, Scholes, Butt. When you have so many at that level, they are ready to fight for their club.
"They have the quality as well, let's not forget. Giggs at 40 is still playing."
