Barca are making a serious play for the Brazil international this week.
"Tito is a great coach, is a guy I admire. In the match PSG-Barcelona in the Champions League I had a brief chat with him and he invited me to go play with them," Thiago Silva told Marca.
"There is nothing in negotiation, with my mind very calm and I'm enjoying my vacation. In football you never know, but I'm happy at PSG, I'm very calm, I speak daily with the President, it is very difficult to get out of there."
