Well, I think he should go, but mainly because I like a bit of a shake up, keeps things interesting (I must be the only Utd fan who is excited about the day Sir Alex steps down, not because I dont love him, just because it will be very interesting...)
Benitez, Benitez, Benitez....
Well, his buying hasnt been all that great. Torres and Macherano great buys, but as someone pointed out, not remotely close to being "unearthed" by Benitez... Not a problem, a manager doesnt have to unearth new talent, getting proven quality is not a problem.
Note this though, those two who, along with Alonso, are I think clearly his best signings, all cost money (Alonso not too much, but £10m or whatever it was was more in 2004 than it is now). Real money. I am not surprised that so many players bought for a few million here and there were not a success.
With hindsight.. He basically should have bought one good player per year rather than so many squad players.
And Aquilani for Alonso is a horrendous swap. Aquilani is not an unknown quantity, he is a good player who ALWAYS gets injured (which is a big problem for a club that rely on their two best players not getting injured). And as someone pointed out, Sneijder was available for a little more than half that price...
And lets not forget, he lost Alonso because of the way he treated him last year...
Benitiez is suffering because some players are out of form to be honest, I have never seen their defence playing so badly. His fault, or one of those things?
In a way Benitez would benefit from leaving, he won the champions league, always does well in it, re-invented Liverpool as a force in football. He could easily spend 3 more years fruitlessly looking for the Premier League title.
Inter Milan would love him, he has proven ability in the Champions League, something Mourinho doesnt really... (sorry don't want to upset anyone... but just look at Inter's current champions league campaign).
But anyway. I think if the club had a chief exec who was in charge, he would be in trouble, but I doubt the owners could agree on such a thing.
As for "the owners have to leave" argument put forward by someone, thats just pointless, its their club, they can sell out or stay as they want, their current issue is their form.
Personally I think Benitez is dull, I am not convinced by his transfers, and woefully little has come out of the youth ranks (as someone mentioned, he has been there a long time). However, I would go as far as to say that in one off games and in cup competitions, there is probably no one better in the world.
(and as someone else said, it is almost shocking that Arsenal get away with achieveing much much less than Benitez's Liverpool in last 5 years or so. I guess thats because at least you can see there is a plan at work, and you either you buy into it or you don't, maybe the problem is that Benitez doesnt give the impression he has a vision).
