Pires is a big fan of the young German.
"Julian is a good player," the Frenchman told SPOX.com. "He's young and has a lot of potential for development.
"When I watch him play, I always think that he fits perfectly with Arsenal's style of football.
"I can see him playing well on the left-hand side or in attack. He could really strengthen the team."
