We've seen that happen plenty of times enough to know it doesn't rule out anything but that won't stop panic it seems
Makes no sense to believe a club would refuse a suitable offer due to starting their preseason when there's 8 weeks left in the transfer window
We've ourselves sold players after they started training like Robson mentioned with Lukaku up there. Clubs aren't going to be inflexible for the sake of it when there's vast sums of money involved especially in this pandemic affected market.
Wouldn't take whatever Zorc says later at face value either, they'll accept in a heartbeat if/when a suitable offer arrives regardless as they've shown numerous times after issuing repeated denials and claiming the contrary
