The Italy international helped Unai Emery's side win a third domestic competition of 2016-17 in Saturday's 1-0 Coupe de France win over Angers, adding to their Trophee des Champions and Coupe de la Ligue triumphs.
However, the Ligue 1 title was surrendered to Monaco and Champions League success eluded the Parisian club once again, following a record-breaking second-leg collapse against Barcelona in the last 16.
The 24-year-old's agent, Donato Di Campli, said earlier this month that talks would be held after the Coupe de France final, and Verratti was quick off the mark with his thoughts.
"It's the club that decides, but I think I'll be there [next season]," he said. "Afterwards we will talk with the club like every year.
"I still have four years left on my contract and I'm not thinking about leaving. I am very happy to be a part of this project and I have always said that winning with PSG is different from winning with all the other teams because I have been here for five years and I would really like to win something very important here in Paris."
The diminutive playmaker conceded it had been a tough season, but praised Emery for helping to develop his game and expressed his happiness at helping to give departing veteran Maxwell a fitting send-off.
"I think I have made progress," said Verratti. "We have a very demanding coach, who always wants a good game and attack. I think I also improved thanks to him.
"Mentally this season was hard, but I am very happy to finish with a trophy and happy for Max that he can finish with a trophy, he already has many. I am very happy."
