Doyle is on a 2 year loan deal, mate.
I'm not sure Gooch can step-up, tbh. I know he's played at higher levels than this with us but that doesn't mean he's a certain level of player. He's a decent league one player on the form he has shown and no more. I don't think he's got the consistency or the end product for the Championship or higher.
I think Neil might be away in January. He's clearly a baller and destined for the top level. I'd be surprised if he's with us for the start of next season regardless of which division we are in.
The rest you have listed should all be fine. I think the step-up to the Championship is also a lot bigger than most people give it credit for and we are still a little short with this squad to be competitive over 46 games up there.
