Paris St-Germain's president Nasser Al-Khelaifi says stars Zlatan Ibrahimovic, Edinson Cavani and Javier Pastore will be at the club next season.
Manager Laurent Blanc, who is on course for a historic domestic treble, will also not be leaving in the summer.
PSG were knocked out of the Champions League by Barcelona at the quarter-final stage, losing 5-1 on aggregate.
But Al-Khelaifi said he was not considering making big changes.
Speaking to Le Parisien newspaper about Ibrahimovic, who has one year left on his contract, Al-Khelaifi, said: "The matter is not even up for debate.
"He will be staying for us for next season, and that is for sure. And that goes for Javier Pastore too."
Al-Khelaifi said Cavani, who cost £55m from Napoli in 2013, was the "future of the club" and said criticism of Blanc was "unfair".
