They've waited too long now, it could be in Roman's mind there's no manager that could rescue a top 4 place from this position so they'd be getting a new manager in just to salvage a top half finish, which is rather meaningless to them. So the real question is who do they want to start next season as manager... If he wants to give Jose another shot, new season, fresh start (of sorts), they may just have to endure this season which is already likely to be a write off anyway even if a new manager brought a change of fortunes.
