Obviously, but they could buy a replacement before the season starts, give him a few weeks of training with the team. Selling De Bruyne in July with 10 days left in the transfer window would give them more options than now. They wouldn't have to worry about actual matches either, not knowing if they can play him the next day in a league game or not. It's in no way comparable to what we have now. How do you prepare for a game on the weekend if you don't know if your best player is still here or not? Or if he is, if he wants to play or just tries not to get injured so that the deal goes through. It's madness.
