Sounds fun.
I expect to see City make some huge signings. Pogba is a good shout and I think Pep will talk some big players into going there.
Liverpool will probably get someone like Gundogan as their marquee signing. He'll live to regret it, but I think Klopp will go all out to get someone in that he knows and feels can improve them a lot.
Chelsea seem to have pulling power simply by being known as a billionaire club and by being in London, so I'd expect them to grab a striker (Lukaku back seems possible) and possibly Greizmann or something, or Mahrez if Griezmann goes elsewhere.
Arsenal seem to keep pulling off one surprisingly top signing most summers lately, so maybe we'll see Isco or someone similarly improbable go there.
Leicester will pick up some bargains and may see Mahrez and Vardy leave, actually, Vardy would fit nicely at Liverpool...
Tottenham will retain their players mostly, and make a couple of good, but uninspiring signings from mid table clubs.
We'll struggle to attract players as they'll see us as being something of a sinking ship and won't want to play under Van Gaal and his 'tactics'. We might be able to get Mahrez if we overpay, but I expect a summer of disappointments. I'd completely revise this if we were to get Mourinho, but we won't.
