3 years? You have to draw the line somewhere. 3 years is fine if you're still on the cusp of achieving your goals, right now we're a million miles off! What if we finish 17th would you still want to allow 3 years? top 4 is the bare minimum (at least it should be for United). No CL, Ed will pull the trigger in May.It never ceases to amaze me what people consider 'giving time' to a manager means. Every fan trots out that soundbite....'we need to give manager X time'....and then 6 months later they are calling for their head citing 'no signs of progress'.
I would say 'time' is three seasons. After three seasons, the manager has had the chance to implement new coaches, new coaching and training methods, new rules and standards and turn over as many players in the squad as they deemed necessary
'Time' is not 14-months. Regardless of whether you think Ole is a good manager, or whether Jose, LvG or Moyes where good managers.....'time' should constitute three years minimum.
