Chelsea or Arsenal to drop out?
I think Chelsea, Arsenal, Man United and Spurs could be vulnerable in the next few years if the other teams got their shit together. Chelsea and Arsenal are a mess behind the scenes it seems, Man United despite their good form are in an uncertain place at the moment and Spurs might stagnate if they stop spending because of their new stadium. However, it all depends on the other clubs outside the top 6. Do they have the belief to challenge the top 6 or are they happy just to sit in midtable?
That's why I think Wolves are best placed, they want more than just midtable security and they look like they will spend big again in the summer so extra matches in the Europa League shouldn't affect them too match. Leicester can do this as well, but probably need a better manager than Puel. If they got Benitez in the summer they would be serious contenders.
