Arsenal striker Olivier Giroud has told Gedion Zelalem to toughen up.
The 28-year-old, who scored in Arsenal's impressive win at the home of the champions Manchester City on Sunday, has revealed he is a big fan of 17-year-old Zelalem.
Giroud told Sports Illustrated: "'I think he could put more aggressiveness in his game.
"I know he's not a strong fellow, but he's a fantastic footballer.
"Technically, he's amazing, and he sees everything before the other players. He needs to play more, but he has fantastic quality."
