Dalglish had been out of work for a decade! Besides, just because he failed it doesn't mean another ex-manager would also fail. Some teams have had more success when a manager has returned than during his first stint.
Hodgson failed and he wasn't an ex LFC manager. Does that mean we shouldn't employ people who haven't worked for Liverpool? You can't just write off a group of people based on the mistakes of one person.
Rafa is our greatest living manager - only 3 years ago he had us ranked as the number one club in the whole world!!!! Not bad considering he had to work under hicks & gillet. Imagine how he'd do with fully supportive bosses?FSG have made an enormous mistake in hiring Rodgson over Benitez. ENORMOUS!
You won't know that for sure, nothing is certain that if Rafa returned he would of picked us back up and returned us to Europe.
But I agree and accept your point to a certain extent. That'll do me!!

I'm not saying RB would have us back in the top 4 by summer and another CL final the following May, but I have 100% confidence that he would be doing considerably better than we have done since he left. No doubt about it whatsoever.
What are your thoughts on his last season here and why do you think we failed to impress that year which lead to him no longer being our manager?
There are only 2 possibilities here:
1) After almost winning us the league the season before, he
suddenly stopped being a top class manager for no reason whatsoever.
2) The ongoing battles with Hicks & Gillet, and Purslow reached boiling point and finally took their toll.
I'll let you guess which one I believe in....
