IMHO, roy evans is the best liverpool manager in recent times
(yes, i'm not kidding), and this is coming from a neutral fan's
point of view. At least the football is more entertaining during
his reign, even though they didnt win anything under him.
Houllier came in shortly after to co-manage with Evans. His
early days in charge are okay. Once he's in sole charge, the
pressure sets in and the football was shit, much worse than
what Rafa is putting up now. (remember the long balls to Heskey and
Owen?) Still remember the classic line from him, "We have turned
the corner!"
i think he turned so many corners he forgot where the hell he
was 
the team with the most flair, playing amazing touch football
became a useless defensive anti-football, long-ball-to-strikers
specialists.. and most of the time, it was boring as hell...
