Mauricio Pochettino is convinced star forwards Neymar and Kylian Mbappe will still be at Paris Saint-Germain next season.
Brazil superstar Neymar joined after being bought out of his Barcelona contract for €222million in 2017, making it the most expensive transfer in football history.
He has been repeatedly linked with a return to Spain, either at Barcelona or Real Madrid, but the prospects of such a move now appear remote as those clubs battle with the economic impact of the COVID-19 crisis.
Madrid have also been linked with a move for World Cup-winning attacker Mbappe, whose contract with PSG is due to expire at the end of next season.
Neymar's deal runs out at the same time but Pochettino, who took over from Thomas Tuchel last month, believes PSG are doing everything in their power to ensure the pair will be lining up for the French champions at the start of the 2021-22 campaign.
"I believe that both will stay, and will stay a long time at PSG," he told RMC Sport. "And I have no doubts, I am very optimistic. The club is working to succeed in keeping them with us."
Asked if he knew this for certain or whether it was just a feeling, the former Tottenham boss responded: "It's a feeling, but it's also what I see. Neymar and Kylian are happy. They are having fun here and I also believe the club is working to keep them."
Mbappe has scored 106 goals and set up a further 54 in 148 appearances for PSG. Since his debut for the club on September 8, 2017, the only players in the top five European Leagues to have registered more goal involvements are Robert Lewandowski (186) and Lionel Messi (206).
Pochettino was full of praise for the France international, who he says has the football intelligence of someone much older than 22.
"The other day I was talking to one of his team-mates about him and we were like: 'Who doesn't love Kylian? His smile, his energy'
"He's young, a world champion at 19. With the talent he has, it's normal to be in love with Kylian. Everyone around him loves him.
"He's only 22 but he's a very mature boy. He looks like a 35-year-old trained man already. He's very mature and very intelligent, very intuitive, and he understands that there are periods in football, ups and downs.
"You have to be positive and you have to keep working to change those difficult times. But we have no doubts. Obviously we are talking with Kylian, but we are talking also to all other players."
PSG will hope to bounce back from Sunday's embarrassing 3-2 defeat to Lorient when they host Nimes on Wednesday.
