The Brazilian defender has put pen to paper on a five-year deal with the French giants after negotiations between the two clubs finally reached a conclusion on SaturdayParis Saint-Germain has announced the signing of Thiago Silva from AC Milan for a reported fee of 42 million euros, according to the Ligue 1 club's official website.
The Brazil international, 27, had been linked with a move to the Parc des Princes throughout the summer, and he has now made the switch to the French capital, where he is expected to be joined by his former Milan teammate Zlatan Ibrahimovic.
He has agreed a five-year contract worth a reported 7.5m euros per year, including 1.5m euros in bonuses, and becomes the second most expensive defender in the world after Manchester United center back Rio Ferdinand.
After previous failed spells in Europe with Dynamo Moscow and Porto, Thiago Silva returned to the continent in 2009 with AC Milan from Fluminense and lifted the Serie A title in only his second season at San Siro.
Although the side was unable to retain its Scudetto shield the following campaign, he appeared to have committed his long-term future to the Rossoneri, having similarly penned a five-year extension only a fortnight ago.
However, with Milan's financial problems well documented, president Silvio Berlusconi confirmed that he had accepted a bid from PSG in the region of 65 million euros for both the Brazilian and Ibrahimovic, despite the Ligue 1 runnerup seeing an initial bid reportedly rejected for the stopper
But while the deal to bring in the Swede remains incomplete, Thiago Silva is now officially a PSG player and will join up once more with former coach Leonardo, and many ex-Serie A rivals, including Thiago Motta, Javier Pastore and Ezequiel Lavezzi.
