Is there any point in which SP would just announce that OG is not coming back next season?
It feels at the moment like the club is being held hostage by OG's public waffling over his future. Like we're terrified to make any moves (such as selling Guehi) that might upset Glasner. The fact is, if OG wanted to come back, he'd already have re-signed. He's clearly leaving.
SP could give OG a final offer and a deadline, and if he doesn't sign it, then announce that we're moving on at the end of the season. Start the search for a new manager, and make some hard decisions on selling Guehi. I feel like the club needs to regain control of this situation.
