Arsenal defender Johan Djourou is backing teenage winger Serge Gnabry for big things.

The 17 year-old won praise from manager Arsene Wenger earlier this week.

"We have a lot of great young guys coming through and one of them is Serge Gnabry," Djourou told the Official Arsenal Matchday Programme.

"He's a very good young player, really tricky, and someone with a big future ahead of him. He has all the attributes to become a very good winger or No 10, and has the right character too.

"If you have that, and don't get carried away, you have a great chance."
