I really don't think who manages makes any difference to the Russian way of control. The managers are just disposable employees.
On the positive, it has seemed to work in terms of trophies since 2003, compared to say the gooners or Utd ie when you look at the 'stability' of having just Wenger for 20 odd years. But now it seems the Glazers have changed tack and are into large speculating -but this a response to their 'noisy neighbours'. I think a kick up the arse for Abramovich an Maria would be if Sp*ds suddenly spent big and over took us. As it is, the board and Abramovich seem happy to cruise along , as long as we're top dogs in London
