Paris Saint-Germain sporting director Leonardo has refused to rule out summer moves for Lionel Messi and Cristiano Ronaldo.
French champions PSG have long been considered one of the favourites, along with Manchester City, to sign Messi should he leave Barcelona on a free transfer in July.
Ronaldo's future at Juventus seems just as uncertain following the Serie A side's early exit from the Champions League for the third season running since he joined.
PSG are believed to be close to tying Kylian Mbappe and Neymar down to new contracts, but they would still likely be in a financial position to snap up Ronaldo.
Asked about the possibility of signing the superstar pair, who have won 11 Ballons d'Or between them, Leonardo said: "Messi? We're focused on this season.
"We are monitoring the market, but we have not started anything about the future, apart from the renewal of our players.
"Cristiano Ronaldo? The same answer."
PSG booked their place in the quarter-finals of the Champions League on Wednesday with a 5-2 aggregate victory against Barcelona.
