The Real Madrid talisman has long been linked with a move to the super-rich Ligue 1 side as he continues to have a strained relationship with his own side's fans.
Ronaldo added fuel to the speculation by whispering something in the ear of PSG coach Laurent Blanc after their Champions League meeting on Tuesday.
And Thiago Silva feels a move is imminent and says the Portuguese attacker would settle in well in the French capital as he already speaks the language.
"I do not know [if Ronaldo will sign] but it's fun playing with such major players," he told RMC. "Ronaldo is the best player in the world. If the club wants him, of course the PSG squad would be happy.
"He is a very good player, technically essential for all teams in the world and especially for PSG, who have a big dream to win the Champions League with great players.
"I think Ronaldo will come. I do not know what happened with Blanc after the game because he did not say but I hope [there were positive talks between the two].
"He speaks French very well, perhaps better than me, and if it happens next year he will have no difficulty speaking with the media."
