I don't think Dortmund will lower their asking price. They will look like a fool if they drop their asking price below 100m for a generational talent. In the non-Covid-19 world, he would have easily gone for 120m+.
If Ed gets this done in mid September (or even later) for anything over 100m, he is a buffoon.
It is so important to allow young players who are playing in foreign leagues as much time as possible to adequately gel in the new team, and for the manager to instil his ideas and understand the new player.
Haggling over a few million Euros can potentially mean a few points dropped. No fun.
If the asking price cannot be met, Ed should say "No" and move on to the next target ASAP.
