Fonte, who left West Ham last season for Dalian Yifang, signed for LOSC earlier this month.
He told L'Equipe: "The Chinese club preferred to recruit three attackers. I had to find a way out. Lille was the first to come forward. I met Luis Campos (sports director) in London.
"I was attracted by what he explained to me about the project, by what would be my role on the team. I spoke with Anthony Lopes, Joao Moutinho. I knew a little about Christophe Galtier. All the info was positive.
"I was aware of the difficulties of last season. But I also know that it is a big club, which won the Championship seven years ago (2010-2011 season). With a big stadium and everything you need to win in the future. I also got closer to my family, who live in London, one hour and fifteen minutes by train. For me it was perfect."
