The Paris Saint-Germain midfielder reveals that he he snubbed the chance to return to Serie A in favour of continuing his career with the reigning French champions
The 25-year-old has been linked with a move away from the Ligue 1 champions throughout the close-season after struggling for consistent form and playing time last term.
The Argentine attacking midfielder, who was at Palermo before his move to PSG, verified that there had been interest from Serie A sides but insists that coach Laurent Blanc has faith in him.
"Juventus, Lazio and Milan? I can confirm there was something with these teams but I am happy at PSG and the club believes in me," Pastore told Sky Sport Italia.
"Having said that, I was very happy when I was in Italy."
Pastore was the 2010 Serie A Young Footballer of the Year and enjoyed two good seasons at Palermo in 2009-10 and 2010-11.
PSG take on Bastia in their first home game of the 2014-15 Ligue 1 season on Saturday.
