Manchester United are ready to make David De Gea an improved offer in a bid to keep him at Old Trafford beyond June 2020, a source close to the Spain international has told ESPN FC.

De Gea, a reported target for Paris Saint-Germain, recently turned down a five-year United contract worth £350,000 a week.

- When does the transfer window close?

Negotiations over a new deal have been ongoing for 18 months but appeared to have stalled, leading to reports that United were prepared to pay De Gea millions to leave in the summer in order to avoid him leaving for free next year.

However, the source said United did not want to sell De Gea at any price, were not prepared to transfer him and would make him a new contract offer.

De Gea reportedly earns £240,000 a week, half what teammate Alexis Sanchez is reported to earn.

PSG are looking for a keeper after parting company with Gianluigi Buffon and are the only club that could afford to pay both a fee for De Gea and his wages. A move to the Parc des Princes would enable De Gea to play in the Champions League.

De Gea had a difficult second half of last season, with the 28-year-old making a number of errors as United missed out on a top-four finish, but remains a key player for Ole Gunnar Solskjaer.

Since joining United from Atletico Madrid in the summer of 2011, he has made 362 United appearances and said last season that he was "very happy" at Old Trafford.

But he looks to have lost his No. 1 spot in the Spain team, with Chelsea's Kepa Arrizabalaga having started the past three games.
