The Ligue 1 champions affirmed on Wednesday that Buffon will leave the club after only one season in France.
Thomas Tuchel's side had a choice to broaden Buffon's stay by a further a year yet have selected against it so as to seek after De Gea.
The Spanish has one year left to keep running on his current United contract and talks have separated.
De Gea has effectively rejected United's best contract offer and now looks sure to leave the Premier League club following eight years at Old Trafford.
PSG are happy to coordinate De Gea's compensation requests and are relied upon to test United's purpose with a £60m offer this summer.This summer speaks to United's last chance to make a huge profit for De Gea else he could rundown his agreement and leave to no end toward the finish of next season.
De Gea has recently suffered apparently his most exceedingly terrible ever season for United and has been a sad remnant of his typical self for as far back as a year.
The 28-year-old just kept seven clean sheets in 38 appearances last season and submitted four mistakes straightforwardly prompting a restriction objective in that time.
