I wouldn't put any money on at 10/1 that we'll finish above Spurs again next season, so there's the only non-relegated team who finished below us doing a leapfrog.
I'm not overly worried right now, a) as I think the promoted clubs all have issues that aren't easily solved - Leeds and Burnley have proven managerial failures at this level and have committed to keeping them for now, and Sunderland look like a Minardi of the early 2000s F1 era, b) we don't know what will happen recruitment-wise, but we do appear to be backing the manager, and he's a good manager, c) we genuinely did look quite good after Christmas, this wasn't a "grind the points out and forget the aesthetics" effort.
Brentford, Fulham, Palace and Bournemouth are all vulnerable to dropping into the mix for me, particular if any or all of them lose their managers. Or they could be decent again, who knows.
West Ham are a mess, Potter has a big job on there. Aaron Ramsdale isn't going to help them if they go down that road.
