If we get relegated I suspect the bulk of the side would form the basis of the Championship squad.
Players I'd keep :
Dubravka (one of the best keepers in the Premier League)
Schar (his passing ability from the back would be worth keeping him around for and his lapses would hopefully be less exposed).
Manquillo (his level, upgrade upon on promotion)
Lewis (looked decent there previously could well be the making of him as a NUFC player)
Hayden (no brainer in that league, where its often about graft as much as prowess)
Shelvey (only if he's the Shelvey under Howe , the one from the Bruce era should never be near a first team shirt again and should be sent to the glue factory)
Joelinton (again could this be his opportunity to bring consistency to his game rather than occasional flashes, the man who played against Brentford looked a nightmare for prem defences let alone Championship)
Wilson (good player but if a silly money offer came in would have to be considered. Think he's going off the boil ever so slightly and in a league where you have to play 46 games and the physicality is more of an issue would we get 15-20 games out of him ? )
Saint-Maximin (suspect he'd be off anyway and may well be worth an opportunity to make a mint on a player who on his day can be a world beater but off his day isn't even a carpet beater. If he stayed, manager has to integrate him into the team in such a way as to get the most out of him, again needs to develop his game so that he offers plenty when he's not hearing the MOTD theme in his head. When on it he would kill players in that league)
Gayle (squad player, always scores in that league)
Anderson (heard this kid is very talented, much like the Hughton promotion season was the making of Andy Carroll an opportunity to see if this lad sinks or swims).
