This is the boards last opportuninty to disprove your theory.
We are fast becoming a 'poor mans' Chelsea.
Whoever takes the job is, initially, going to face some form of resentment from a large number of fans, following the way Kenny left us. This will only get worse if performances and results don't go our way. He's also got to win over established players who are likely to get difficult if they don't agree with tactics, etc..
We then have FSG who he may feel will dispense with his services if he hasn't hit the top 4 in his first 2 years. This, amidst rumours that they are looking to cut back and reduce spending. What amount they will spend must go on potential, rather than the finished article. Kinda makes you think that if Chelsea can't make the top 4 with a bunch of expensive, highly paid world stars, then how can we do it with potential.
Then we have the fact that the new manager won't even be the master of his own destiny. New players will be purchased by a yet unknown Director of Football. If the team fails, then it becomes a matter of who carries the most weight rather than one of accountability. Will it be because the players we may sign aren't up to it or will it be a case of poor coaching and tactics. We've tried partnerships before in Roy Evans and Houllier; that didn't work. We also tried with Kenny and Commolli; that didn't work either. So our chosen way forward has only a history of failure.
So considering all of this, if you were a well respected manager, making your own decisions at your present club, would you leave to become manager of Liverpool? I wouldn't, and it seems that a number of candidates feel the same way, hence the reason that they've turned us down.
Like i said, the position is completely untenable.
