I have a gut feeling they will stay up. They are a poor quality side but there is still spirit in the players and the fans. Just a couple of decent signings would make a difference. Could they get someone like Ward Prowse, Trippier, or Coady on big wages? They could sign some people on 12 month contracts. I think Norwich, Burnley, and Watford are going down (perhaps even Leeds). It will be close though.
If Wilson and ASM are injured for a while then I can see them dropping.
With those 2 they may have signed enough players to keep them up. They've now got to sign players just to replace those 2.
Wilson looked like he tore his achilles, which striker will they be able to sign in January better than him?
I've seen Newcastle fans on their forum mention Aubameyang, Martial, Vlahovic. They're all living in cloud cuckoo land.
