And the Red Devils are said to be doing everything in their power to get the deal done.
Ex-Manchester City youth Sancho has emerged as a top target for United.
The club are pushing for the teenager to make a return to Manchester following his huge success in Germany.
At Borussia Dortmund, Sancho has got the experience of top-level football he desired, as well as Champions League action.
But the Bundesliga title-chasers now face a real battle to keep hold of the 18-year-old ahead of the summer transfer window.
While Dortmund have expressed publicly they have no intention to sell, United are remaining persistent.
The London Evening Standard say a United source has claimed: “They are doing everything they can to sign him.”
The huge update on Sancho’s future comes as:
“Sancho is seen as the ideal fit for the squad at Old Trafford”
A bid from Manchester United in excess of £80m is expected to be enough to seal what they consider the ‘perfect’ signing.
Sancho is seen as the ideal fit for the squad at Old Trafford, with the Red Devils in need of a natural right-winger.
His age also suits United’s approach of now targeting younger talent looking ahead too.
Solskjaer is still to be confirmed as the manager beyond this season, but he has played a big role in discussions over United’s transfer strategy.
Sancho’s rise in Germany has apparently convinced the Norwegian and the club’s scouting department he is the real deal.
Whether Sancho is ready to head back to England so soon, having left City for Dortmund in August 2017, is still in question.
But one aspect United can feel relaxed about is their neighbour’s influence in any approach for their former player.
There was no clause inserted into Sancho’s contract when he left City for Dortmund which means a subsequent move to United would not see his old side entitled to a hefty sell-on clause.
This is the case with Brahim Diaz at Real Madrid, as City are entitled to 15 per cent of any future sale following his £22m switch to the Bernabeu, but that would rise to 40 per cent if he returned to a ‘Manchester-based’ club.
City do have a buy-back option from their £9.1m sale of Sancho to Dortmund, however, the London Evening Standard add the reigning Premier League champions are highly unlikely to break their transfer record to re-sign Sancho two years on.
United fans could get a closer look at Sancho on Friday (7.45pm) if he lines up for Gareth Southgate’s England when they host the Czech Republic at Wembley in their first EURO 2020 qualifier.
