Speaking on Friday, the French sportsman said:
"Look, I haven’t read the book and I certainly won’t read it. I cannot comment on that. I talk about football and that’s all I do. I’m not in a destructive mode, ever. I’m more constructive and I cannot comment on that because I’m focused on tomorrow’s game and how we want to play football.
"What is amazing is that has nothing to do with our game tomorrow. I personally am just focused on doing my job well and respecting everybody else.
"I do not want to especially comment because we play Chelsea tomorrow. I have no personal problem with anybody, I respect everybody in our game and I don’t feel I comment a lot on other teams.
"Sometimes I just say what I think, but that is part of the way I am."
