The Brazilian left PSG on a free transfer after eight years at the Parc De Princes.
And the 36-year-old has told FourFourTwo that his former club did not contact him over a contract extension or even organised a farewell.
"They never offered me a single thing; not even, "Thiago, do you accept €1 to stay with us?" Absolutely nothing, which was very upsetting," Silva said.
"There's something worse than that, though. Even in the middle of a pandemic, they had three months to plan a farewell, but nothing was done. Man, I wasn't there for only one season, or a few months – it was an eight-year spell as a captain who lifted a number of trophies at the club.
"I deserved much more respect than that. The same thing happened to [Edinson] Cavani. That said, I'm really grateful for the things I experienced there. The final bit aside, I was happy and always well treated by everyone."
