I agree we're all basically just guessing with this. And tbh the whole affair makes no sense to me anyway. But if you did sit down and try and apply common sense, Chelsea could keep the relationship open by just saying to the lad, and to Everton, that they are pulling out because of the injury and want to re-open negotiations in January. Nobody would blame them for that, not even Evertonians, well reasonable ones anyway. And there's absolutely no reasonable explanation as to why , if that happened, Barkley or his agent would want him to take the blame and all the backlash that goes with it. Even if he wanted to keep the door open to spurs his agent could do this with a phone call.
For me it isn't about conspiracy theories, I'm trying to apply common sense and nothing adds up.
