United are desperate to convince the £ 89million Frenchman to sign a new deal ahead of the new season after being forced to trigger a 12-month extension of his current deal.
But their attempts to persuade Pogba and his agent to give up the peak years of his career are deadlocked.
The prospect of the 28-year-old leaving Old Trafford for the second time, after honoring his contract, has turned into a nightmarish scenario.
And that will have implications for United’s other transfer activities.
Mirror Sport revealed this month that United were quoted £ 81.5million by Borussia Dortmund for England winger Jadon Sancho.
And his arrival now looks even more likely after agreeing to hand over most of their fees to the Bundesliga club up front.
Ole Gunnar Solskjaer treated Pogba with care and refused to get involved in any exchange of views with super-agent Mino Raiola.
But United have made it clear they will look to sell Pogba now rather than allow him to leave as a free agent next summer.
United once slapped a £ 150million valuation on the midfielder to fend off Real Madrid’s moves. They would have the chance to harvest even a third on the market this summer.
Pogba has agreed to appear in an Amazon documentary about his life next season – and the drama of his negotiations with United should now take center stage.
