Johan Djourou is backing Switzerland teammate Granit Xhaka for success with Arsenal.
Djourou, who spent a decade at Arsenal between 2004 and 2014, is sure that Xhaka will become a firm fans' favourite in defensive midfield.
The Hamburg centre-back said. “He's a top-class player with lots of qualities. I think he'll do Arsenal a lot of good.
"There's huge competition - but I am sure that he has the quality to impose himself. He brings calmness, his ability to play long passes, precision and aggression."
