Argentinian offensive midfielder Javier Pastore celebrating what he terms his best season in Paris Saint Germain's historic campaign winning four trophies will be with them till 2019 after extending his contract on Monday.

The 25-year-old -- capped 19 times -- was suspended for Saturday's 1-0 win over second tier Auxerre in the French Cup final but it failed to dampen on a personal note his overall assessment of the season.

"I'm very happy. This has been the best year of my career," said Pastore.

"This season was special because I played so much and I felt especially comfortable out on the pitch.

"I'm very proud of my season, and also of all my teammates because without them, I couldn't achieve anything," added Pastore, who scored six goals in 51 appearances but also set up many others for his team-mates.

Pastore, who was the first big name to sign for the Paris club under its Qatari owners in 2011 from Italian side Palermo for 43million euros ($47million), said the historic campaign was terrific but he had further goals to accomplish with PSG.

"I hope to keep winning titles here and to play a champions league final with this team, that's my main objective now," said Pastore, who has been selected for the Argentina squad for the upcoming Copa America.

"I think we can get there in the next few years, why not next season? I hope so. That's my aim, to win the champions league, to play a final with Paris Saint-Germain is my focus."

Pastore has accrued three league titles, two League Cups and a French Cup winners medal since arrived at the club.
