Why so hostile? Can you imagine that BVB did not want to let Sancho go last year? Sancho helped a lot with the CL qualification this year, this alone is worth a lot more than the difference to last year. The soccer world changed as well, look at the other transfers this year, nothing big above 30 Mio € yet (with the exception of Sancho of course), Barcelona in shambles, Bayern even with a lot of money is not doing anything big, Mbappe leaves PSG without even a fee, you can't compare pre Corona with Corona, because I can assure you that 5 years earlier we would have gotten the 120 Mio.
Anyway, good luck with him, don't treat BVB as hostile, because they want a lot of money for their star player. Which team wouldn't?
