Owen Hargreaves believes Kylian Mbappe and Neymar will stay at PSG if they win the Champions League.
The Parisian club are hoping to keep their two star attackers, with Mbappe consistently being linked with a move to Real Madrid.
Neymar has also been rumored to fancy a return to Barcelona in recent summers.
Former Manchester United and Bayern Munich star Hargreaves said on BT Sport: "Neymar and Mbappe only have a year left on their deals. So, it feels like this is a huge moment for them.
"I'm sure Mbappe is thinking he could easily stay there or he could easily go play elsewhere - whether that be Real Madrid or Liverpool.
"For Neymar, he is 29 now. He could go back to Barca or stay at PSG.
"This is a huge moment for them. They need to win the Champions League. Ligue 1 is not enough.
"If they can win the Champions League, maybe those guys stay and then they can build something fresh with Poch [Pochettino]."
