I don't get how Jagielka makes this list, at all. He's been out second choice centre back since he signed. Last year if Egan wasn't available, he played. This season we can add Ampadu to the mix, but he's still needed as cover. Guatenteed if we hadn't extended him and Egan got injured, we'd all be criticising not keeping an experienced centre back, as a cheap option.
Rodwell I suppose is a cheap utility man, doesn't add much though. We've struggled defensively and in midfield and he can't even make the squad, think that says it all.
The goal keeper situation is an odd one, but I'd guess we were worried we wouldn't get one out main targets. I'm assuming the plan was to then move Moore on, but he picked up an injury. Can't imagine it's too easy to move an injured keeper on, if you need a keeper they need to be available. I'm sure he'll move on in January.
