“I thought of Özil, the world champions, Lacazette, Aubameyang and many more. Of course, these are the players who sprang to mind because I used to watch them when I was at Lille.
“Also, Lacazette used to play for Lyon and so I have had the opportunity to play against him. It will be an honour to play alongside him.”
Head coach Unai Emery said: “Nicolas is a highly-rated and talented winger who was wanted by many of the top teams in Europe.
“Signing a top-class winger has been one of our key objectives in this transfer window and I’m delighted he’s joining.
“He will add pace, power and creativity, with the aim of bringing more goals to our team.”
