You just spent 37m was it? On a player with only 5 pro games to his name. And if I'm Dortmund I would use that against United, if they try low balling. He still goes for 70-80m.
On a different note, I do think Sancho does come back to England because of the whole pandemic he has barely seen his family and that seems to of played a apart in his loss of form. Which kinda picked up after Christmas as he managed to link his dad in Dubai during the Christmas break.
I still doubt very much that Man Utd would pay anything like 100m for Sancho.
On a personal note, hopefully we don't.
As for Diallo
This is from Wikilpedia:
"On 5 October 2020,
Manchester United agreed to sign Diallo in January 2021, pending the agreement of personal terms, passing a medical and the issue of a work permit.
[17][18] The reported fee was of €25 million – €40 million including bonuses.
[19] Diallo officially joined on 7 January 2021, on a five-year contract with the option of an extra year.
[20]"
This from transfermarkt: 15m EUR player + fees of 21m EUR
This is what the Manchester Evening News says
"The MEN understands United have agreed to pay
£19m up front, with £18.1m in add-ons, for the 18-year-old Ivory Coast winger. The overall fee was initially believed to be around £27.5m but rose with agent's fees."
