Cristiano Ronaldo will deliver Manchester United a snub should he leave Real Madrid.
United boss Louis van Gaal is interested in bringing the 30-year-old back to Old Trafford were he to become available.
But Ronaldo has apparently given his word to PSG that he will only quit Real for a move to the French giants.
"Cristiano has told those closest to him that he wants to stay at Real," a source told The Sun.
"But if for one reason or another he leaves then he will only go to PSG.
"The decision has been taken and he was in no mood to entertain any other clubs.
"He wants to live in France, he likes Laurent Blanc [PSG boss], he has a great relationship with Nasser Al-Khelaifi, the club president and he knows life in Paris will simply be sensational for him."
