I'm don't think Leeds will even stay up next season, even if these new financial rules about spending a % of your revenue come in, which would give Leeds and Sunderland an advantage over us and Burnley owing to their higher revenue, ticket sales etc.
All of the top 4 are easily better than Southampton, Leeds are probably better than Leicester and maybe on par with Ipswich, we're as good as Leicester but worse than Ipswich.
The scary thing is, that Wolves (only 5 pts clear) are probably better than all of the top 4 and to have a chance of staying up next season, we'd have to be better than them.
Easier said than done but a lot can change between now and next season.
