If it's a swift return to the top four you're after, who's the most likely to get it for you? This is a serious choice for you, you're mortgage depends on it - maybe your wife's virtue!
Guus Hiddink
José Mourinho
Fabio Capello
Rafael Benitez
Van Gaal
I think in practice the first 3 are simply not available due to money - both their salary and their demands for transfer funds.
To get quickly to a top four I think Rafa is a clear favourite.
OK, OK, OK so a medium/long term structure is more important to you.
So you need a young, hungry manager to work under a DoF.
Martinez or Rodgers. Either one - no problem.
You need a DoF.
Johan Cruyff
Van Gaal
Txiki Begiristain
Honestly can't believe Cruyff would come.
Van Gaal as DOF is likely to be a short term regardless of who the manager is.
So, for me,
The return of Rafa as manager
or
Txiki Begiristain/Rodgers combo
would, IMHO, be viable solutions. I'm a Rafa fan so I'd prefer the first.
Maybe Rafa could work long term with a DoF - I don't know.
Maybe our top players would stay under a Txiki Begiristain/Rodgers regime - I don't know.
Certainly the much fancied Van Gaal/(Martinez or Rodgers) combo seems to address neither of the two possible priorities of FSG.
