The contract of De Gea, 28, at Manchester United ends in June 2020 and it is unclear whether he will sign a new contract.
PSG are rumoured to want to sign De Gea, and, according to 'The Sun' the French side will offer the goalkeeper a contract worth more than 400,000 euros a week. De Gea's decision is likely to be swung by Champions League football, with United in a top 4 battle to play in Europe's top flight competition next season.
Real Madrid are also considering an offer for De Gea, whether that be a transfer fee or a swap deal with Thibaut Courtois. In any case, all is up in the air, and United may look to sign Oblak, as Solskjaer has handed the United board a list of potential replacements for De Gea.
According to the 'Sunday Express', Oblak and Jordan Pickford are two keepers that Solskjaer has a particular fancy for. The Everton keeper would be more expensive than Oblak, especcially as Everton may look to allow him to leave after his scrap in Newcastle last week.
Oblak, together with Ter Stegen, is the most expensive goalkeeper in the World, It is thought that he has a value of 80 million euros, although he has a release clause of 100 million euros.
