The French tactician admits it is a juggling act to maintain the interest of younger players if they are not always playing first team football and used the example of Jack Wilshere, who spent part of last season on loan with Bolton.
"I always wanted to develop the players I have. For example we have (Abou) Diaby, we have (Alex) Song, we have Denilson in this position, we have bought Aaron Ramsey - 18 years old - in this position, and now Jack Wilshere develops in this position," Wenger said.
"The problem when you develop a young team, for example we have Jack who was born in 1992 - 18 years old - is that if I don't make room for him he will go somewhere.
"People will say to me: 'Why did you let him go? Look at what a good player he is.'
"But if you don't play him (he will go) and that's the tricky situation of developing young players."
