Fair enough.
However I would disagree that people don't say nice things about him. The only people who seem to bad mouth him were players on the fringe or were on their way out (Riera and Yossi). These same players who left the club have hardly played since they left or have failed to recapture their best form (Alonso aside).
Players like Mascherano, Torres, Kuyt, Agger, Reina have all complimented Benitez and you could argue that these are all top class and are still performing at a high level.
I don't believe that being a great man manager is simply someone who has a laugh and a joke with you. Rafa certainly isn't that type but if you had the right desire and attitude to improve, then he would give you all the time in the world. Gerrard may have questioned Rafa's techniques but Gerrard's best playing days were under Rafa (goals and assists wise).
With regards to opinions outside our fanbase, Rafa is highly regarded around Europe. It's only in England where he doesn't get the respect he deserves - our country would rather kiss the arse of someone like Moyes and Pulis, 2 men who haven't achieved anything tangible.
Is he? I doubt he's got the best reputation in Italy!
