Mbappe has been linked with a blockbuster transfer to LaLiga giant Real Madrid, though the 20 year-old France international reassured fans last month that he would stay in Paris.
However, Mbappe cast doubt over his future after being crowned Ligue 1's Best Player and Best Young Player of the Year.
"This was the only title that I was missing. I am truly very happy," Mbappe – who has scored 32 Ligue 1 goals this season – said as he received the award.
"I want to thank all of the people who put together this league. I succeeded in adapting in my first year, to change position this year.
"There were some disappointments, but that is part of football. This is a very important moment for me.
"I am arriving at the second turning point in my career. I have discovered an enormous amount of things here.
"It is maybe the moment to have more responsibilities, maybe at PSG, with pleasure, or elsewhere for a new project. In any case, thanks everyone."
Mbappe, who has won back-to-back Ligue 1 titles since arriving from Monaco, later added: "I said what I had to say. When you are in such an occasion you can send messages, I think I have sent mine.
"If I speak more it will be too much and that is not the message I wish to send."
World Cup winner Mbappe's two-goal haul in the 4-0 rout of Dijon saw him become the first Frenchman to score 32 league goals in a Ligue 1 season since Philippe Gondet did so for Nantes in 1965-1966.
In total, Mbappe has netted 38 goals across all competitions for PSG – which was remarkably eliminated by Manchester United in the Champions League last 16.
