I think expecting Dalglish to win leagues for Liverpool in this day and age because of who he is, is very sentimental, the game has moved on now and there are bigger more powerful Clubs than us in the league...
How about chilling for a bit and seeing if Kenny can get playing footie deserving of our club before we hang him for supposed sins committed 21 years ago, before we start wondering where he might take us? That he is ambitious should be to our benefit; our last manager aimed for mid-table and achieved his aim, and you're happy with that somehow. "Aim for sky and you'll reach the ceiling. Aim for the ceiling and you'll stay on the floor." - Shankly.
The only potential problem is that FSG may have a specific manager in mind to sign in the summer, but if Kenny get us to finish 6th or higher there will be resistance from the fans to replace him. I think FSG knew that when they signed him on, and I'm sure now they're hoping that he over-achieves so that keeping him will not need any discussion. I believe that Kenny is a man of integrity and will step aside if asked, but you know he'll be looking over his successor's shoulder all the time; so that man will walk into a position with a lot of pressure. Whoever replaces Kenny will need to make peace with him first - which is part of why I mentioned that guy needs to restart the boot room philosophy in order to get Kenny on board in an advisory role. That way we're all on the same time and egos don't get involved. A winning team is a harmonious team; we've had no harmony for a long time now, and that's part of the reason why were 12th.
(Aside: I said a few months back that reinstating tradition for tradition's sake is stupid/old fashioned, and I stand by that, but one or two of our traditions still have merit, and we could learn from those)
