Coady's decision to move to Everton hasn't cost him anything, but gained him a place on the plane to Qatar. He may be vaguely passable in a back four that operates a low block, but what got him into the England squad was his excellent performances as a star shaped block in a star shaped hole. What *kept* him in the England squad was his professionalism and character, coupled with the fact he was still playing in the Premier League and doing 'OK'. Now, England or not, he'd still be on the bench now, whether it be here or at Goodison, so I think he can look back and know he's done the right thing for his career and his family.
Obviously for 23/24, it's unlikely that either Wolves or Everton (or indeed England) will want him in their squad, but that doesn't mean he can't add value to low end Premier League 11/18. I can't imagine he'll have stupid wage demands, and I'd be very surprised (and disappointed) if we let a few million prevent him from choosing from the 2/3 clubs that will want him as part of their squad.
Ignoring the debate on his ability or otherwise in this system or that, let's not forget that he is an absolutely diamond bloke, an incredible professional, and did an excellent job for us both on and off the pitch. He should be allowed to leave with massive gratitude and well wishes, and be treated to a stonking reception should he visit Molineux with his new team
