Bielsa, Stramaccioni or Meulensteen for me. McLaren would probably be good if he didn't have so much baggage. It would probably be an appointment doomed from the start. The only thing that could save it would be if the entire fanbase had already accepted relegation as a given. Anything better would be considered a bonus.
Stramaccioni would be my choice as well.
His record at Inter doesn't look that great on paper but he had a very average Inter side playing excellent football until he was fucked over by the board in January (sounds familiar) and had an unbelievable injury crisis to deal with. Would be a massive gamble (as pretty much every appointment would be) but I think it would be worth the risk.
