Freddie Ljungberg says Nicolas Pepe has 'worked his socks off' since arriving at Arsenal.
The Ivory Coast international was excellent in the second-half of Arsenal's come-from-behind victory over West Ham United on Monday, scoring the second goal in the 3-1 win.
"Nicolas is an amazing footballer," Ljungberg told Sky Sports after the game.
"It's not easy to come here from the French league. He worked his socks off and he will get better and better."
