Agreed. Dortmund get some stick on this forum, and I dislike them with their "You love to see it" stuff - but at the end of the day, we're the arrogant ones to disregard Dortmund's stance of what they value him at and us thinking we can just delay until they "succumb to our whim" and accept a weaker deal. They have no reason to sell. They have an exciting, young team that will have another good run at Bundesliga and have a crack at going far into the Champions League. They'll get even more for Sancho next season.
We knew how much they wanted - it's not an obscenely out-there price for a player of his quality and potential. It's not as if they've placed a "£700million" price tag on him.
If we weren't happy to pay close to what they wanted - then we should have walked away months ago and got a suitable replacement.
