The former Palermo man is very happy to be linking up with his compatriot, and hopes that the ex-Napoli forward can strengthen their attacking options
The former Napoli forward moved to Parc des Princes for a fee believed to be in the region of €30 million, following in the footsteps of his compatriot, who took the well-trodden path from Serie A to the French capital 12 months earlier.
And Pastore, who arrived from Palermo, is delighted that his club have signed such a high-profile player, and is excited to play alongside the former Estudiantes forward.
"I'm very happy with his arrival because he is a friend of mine," he told the club's official website.
"I got to know him in the national team, and his coming here has made me very happy. It's certain that he will bring us a lot going forward, and that is decisive for us.
"We know that he has great potential and that he will be an added asset to us."
Paris Saint-Germain finished second in last season's Ligue 1 table, just three points behind surprise winners Montpellier.
