David de Gea's Manchester United future is looking increasingly bleak after Ole Gunnar Solskjaer took his goalkeeper quota to four.
De Gea, United's No.1 for the past decade, was deposed by Dean Henderson last season, although he retained his place for the Europa League campaign.
But with United having confirmed Tom Heaton's return on a two-year deal and handed a one-year contract extension for Lee Grant, De Gea looks to be on his way this summer.
United boss Solskjaer admitted the sharing of goalkeeping duties between De Gea and Henderson was unsustainable for another campaign, with both desperate to be first-choice.
England keeper Henderson, forced out of Euro 2020 by injury, is seen by Solskjaer as United's long-term No.1, with De Gea now out of favour for both club and country.
Having lost his Premier League place to Henderson, De Gea has suffered the same fate with Spain, Atletico Madrid's Unai Simon given the No.1 spot by boss Luis Enrique for Euro 2020.
Although De Gea will not be prepared to be back-up to Henderson for a full season, United are likely to find it difficult to shift their highest earner, who is on £350,000-a-week.
If they are to offload De Gea, most likely on loan, United are almost certain to have to pay half of the Spaniard's wages, just as they did when Alexis Sanchez went on loan to Inter Milan.
De Gea, 30, has made 441 appearances for United, keeping 155 clean sheets and winning the Premier League, FA Cup, League Cup and Europa League during his time at Old Trafford.
Returning to United, Heaton said: "It feels like coming home. I'm looking forward to coming in to compete with the other goalkeepers.
"I've got my eyes firmly set on trying to get into the team and I'm looking forward to getting started on that journey."
