Rodgers said it himself when he was appointed. "Some fans will never be happy, if we win 4 nil they say it should of been 5". ged fits perfectly here.
I dont think there is anything wrong myself with always demanding more from the team, all the greatest managers in the world never rest on there laurels they are never happy and always strive for improvement. If Liverpool ever won a League again which they wont, I would say all very nice that but I want to win it again, again and again, this is the mentality we had back in the day, it then stopped and we started to drift to the point were we now dont win Leagues, no longer play in the Champions League and the best we can hope for league position wise is anything between 7th and 12th. So you see, always demanding more and never settling is not such a bad thing as it keeps the competative edge, all winners want more.
