The PSG defender denied reports yesterday of agreeing personal terms with Barca.
"I'm his friend and I talk a lot with him. His arrival would be very good news.
"I think it's a matter for both parties.
"If it were up to Thiago Silva, he'd be here. But it not only depends on him. PSG has also invested heavily in him and if Barca wants him, they need to find an agreement with the club."
