The Brazilian defender's representative stated that the two clubs are currently in negotiations, but admitted to being unsure about the Rossoneri's intentions
"There are negotiations between Milan and Paris Saint-Germain, but I do not know if the Rossoneri will sell him," Paulo Fernando Tonietto told Tuttomercatoweb.
It is understood that the French capital club are willing to splash out 42 million euros for the defender, a fee that could rise to as much as 50m euros depending upon his success at Parc des Princes.
"If Milan decides to sell him, what I can say is that this is the best moment in Thiago's career," Tonietto said.
"It is true that the biggest clubs in Europe have contacted Milan about him. We are talking about one of the most important players of their squad."
Earlier in the week, PSG sporting director Leonardo confirmed his side's interest in the Brazilian stopper, who joined Milan from Fluminense in 2008.
