The Argentina midfielder rebounded from a lack of form and confidence to star in Saturday's success, with Carlo Ancelotti also praising the 23-year-old
The former Palermo star, who transferred to the Parc des Princes in the summer of 2011, was a key player for the club under Antoine Kombouare, but has so far failed to live up to his price-tag under the guidance of Carlo Ancelotti.
But the 23-year-old has recovered from his dip in form which saw him dropped to the bench, and played a starring role in Les Parisiens' 4-0 win over Evian on Saturday evening.
"The confidence is coming back, and I feel much better than last week. I have more freedom when I'm alone," the Argentina international told RMC Sport.
Pastore also sought to downplay rumours of a loan move back to Serie A, insisting that he is doing well in the French capital.
He continued: "That big clubs like that are interested in me makes me happy. That means I work well. But it is not a possible opportunity for me because I feel very well in Paris. Because it is a difficult time [I do not think] we must immediately change clubs."
Meanwhile, Ancelotti has also praised the player, and insists that Pastore's re-emergence is down to his change in attitude.
"He changed a lot because his attitude has changed on the ground," the 53-year-old told Sport 24.
"He began working for the team to use his qualities for his team-mates. This is really a metamorphosis."
Paris Saint-Germain sit second in Ligue 1, two points behind Olympique Lyonnais with an extra game played. They travel to Valenciennes in midweek.
