"There are some youngsters doing very well for us," Wenger told the official Emirates Cup programme. "You've seen Jack Wilshere who is catching the eye at the moment. He is surprisingly mature for his age, you forget how old he is when you see him play. But there is also Jay Simpson, Mark Randall, Gavin Hoyte and Henri Lansbury who were with us out in Austria. All five of them are good players though, which is why I took them to Austria. All those players will make a career, and hopefully at Arsenal."
