The Argentina international says he is pleased to be part of the ambitious Ligue 1 side's project, and has set his sights on winning silverware
The attacker brought his five-year stay with Napoli to an end to join the French side on Monday, and he wasted no time in expressing excitement over the Ligue 1 outfit's "project".
"PSG's project really attracted me," he told reporters at a press conference.
"I have the opportunity here to express myself at a club that's on the rise and that will continue to make steps forward. I have the chance to win titles here and I want to play a part in future successes.
"Ligue 1 is a very competitive league. It is a new challenge for me and I really like that. Paris Saint-Germain are a club where I can further develop.
"It's a club that will only become more important in the next few years. And Paris is obviously a city where everybody wants to live.
"[Javier] Pastore told me a lot of good things about the club and about the city. We talked about PSG when we were with the national team. I will try to have a close relationship with the fans, just like I had at Napoli."
