The fallacy is that most people dislike Redknapp because of results. Most people have problems with him because whenever things were going right he was in the forefront beating his own drum. When they weren't going well it was someone else's fault. When it was going well it was "us" when it wasn't going well it was "them".
Still, the worst thing was him entirely checking out on what should have been our best season since the early 80s when the England job came open. Everyone including the players could tell he didn't give a toss you could see it on their faces and they even were mentioning the stress of it openly. Then him trying to crawl back when it didn't work out.
It wasn't his managerial work it was that he was extremely un loyal, mate.
Which I have no problem with....but how does that belittle what he achieved on the pitch?
