"I really wanted to come here," he told L'Equipe. "You have to make choices in your life, and this wasn't the easiest for me, but it excited me.
"Firstly, we are playing for the title, and also it's a young team of good guys who play good football."
"I like playing in the middle, with the freedom to dictate play," he added.
"For now I am on the wing, opposite Eden Hazard and linking up with Dimitri Payet.
"The idea, in time, is to come into the central three and direct our attacks from a bit deeper. That's where I started, it's natural to me.
The 29-year-old has not played for his country since last summer's World Cup but he said: "I hope Fabio Capello watches Ligue 1. If I can get a recall to the national team, I'll be the happiest guy around.
"But firstly, I want to play regularly and try to help Lille win a trophy."
