The point I was making is that when Chelsea wanted a new manager, they went for the manager of the European Champions. When Liverpool wanted a new manager, they went for a manager with a proven track record in La Liga and with european pedigree. I don't believe that we should be looking at a one-season wonder or an SPL manager with only limited success (who, incidently, Lou Macari described as ideal for City. Say's it all, really).
I think it is pointless to make comparisons with United as we are today and United as we were in 1986, and certainly football itself has moved on dramatically. The jump from SPL to United or Everton to United is, in my opinion, too big to make, even if just for the size of the infrastructure.
