1. Strenght in depth in their squad
2. Upcoming youth to replace old players or when massive injury crisis
3. Actual quaility in their strenght in depth that their sub midfielders and striker score regularly or at a descent rate, the spark that Suarez, kuyt have
4. Manager who gets it right tactically and at man mangement- making attacking subs, or changing formation during a game when it looks obvious nothing is working.
5. Experience- personaly don't think we're too short of that at the moment.
6. Good rotation of squad for easy matches which doesn't backfire due to strong youth and squad.
7. Having a foul mouthed git as a manager to strike fear into referees to get decisions, and players playing when needed- the hairdrier.
8. Manager to have respect at all levels of the club, owners, staff, players, youth, fans, sports broadcasters and journalists.
9. Good owners to regenerate squads every year to form a new squad every 5-7 years.
10. Good eye for talent
Lol can't think of anymore but I think you can find all the reasons why we have failed under all previous managers in that list.
Dalglish so far-1,3,6 again not his fault as mainly he inherited all of Hodgsons problems below but has narrowed the problems down to only 3.
Hodgson- 3,4,7,8,9,10
Benitez- 1,2,3,4,9,10 although he tried to fix every problem and in the end suceeded but the results only came after he was sacked.
Houllier- 2,3,6,10 he left due to having too much time at the club and health reasons.
most managers failed due to 3,4, or 10.
