Both Roy Evans and GerardHoullier had five years to restore the fortunes of the club,and neither suffered the kind of insult from one of his own board Benitez must tolerate today.
If Moores and Parry don't act instantly, the long-term repercussion should not be underestimated.
Sunday's defeat at Old Trafford was deeplydisappointing to everyone,not least Benitez, but to attempt to shift the blame for the club's faltering start on him is shameful.
There are deep-rooted problems at Anfield, which everyone at Liverpool is fully aware of but prefer the fans not to consider.
Benitez has no control over the Liverpool Academy, which has produced just one first-team regular since the move to Kirkby in 1999.
The search for investment has been a painful, and sometimes embarrassing process, and although Benitez's transfer kitty may compare favourably with teams with aspirations for UEFA Cup qualification, they're light years behind Chelsea and Manchester United.
All these matters are the board's, not the manager's, responsibility.
The unnamed source, so impatient for success, would be wise to practice his response to such accusations if shareholders decide an extraordinary general meeting is justified to remove him.
