Don't have time to translate it whole, so just a summary:
He says he didn't talk about the Fontang affair at first, because it's his character, he keeps all things inside. But of course it affected his game, because after the first point he felt like he already lost the match and just wanted it to be over.
Then he talked about it in Monte-Carlo and things started to get better. Now his father and his lawyer take care of that thing and he can focus on tennis. He says Mouratoglou gave him the "pleasure of playing tennis again".
They work a lot on his physical condition and working on some things, but it keeps time to fall into place.
It sounds positive. Let's hope the smile will stay. Anyways, sorry for the crappy translation
