Paisley created something that endured we can't judge fagan he was in too short a time. Dalglsh did create a top team (with support) in 87 / 88 but within 12 months it started to fall apart. The trajectory was downwards. His other short term success was also achieved with overwhelming advantage namely jack walkers unlimited chequebook. Again it fell to pieces after a short period. This indicates a manager who has a lack of ability and cannot succeed without overwhelming advantage and even then cannot sustain it. His career at Celtic, Newcastle and the second coming at Liverpool was laughable. He has done untold damage to all the clubs he managed including Blackburn and his wasting of owners money is unsurpassed.
I hate the man. If he had honour he would certainly not be back at Liverpool,for more handouts. If he had honour then he should stick to the golf course he has tens of millions in the bank.
Paisely, Fagan, and Shankly all had fat purses. I won't argue that he's better than Bob or Bill. Those are the two greatest we ever had and probably ever will. But Rafa only ever won the two trophies (although that CL final is the most special match I have ever watched) and never the league, and Evans' side, despite being entertaining, were full of sound and fury, signifying nothing. Houllier won several trophies, but he made even more blunders than the ones you accuse Kenny of making. Fagan, as you say, was not there long enough to judge. Kenny is the de facto third best of an exceptional group. He continued a reign of success, but when a successful manager steps down, it's not always smooth sailing. Look at Fergie's retirement. Coming off 26 years of the most successful manager the prem has ever had, Moyes took over a club that has been more or less winning the title or something else at least every other year. He was hand chosen, but the transition was still not smooth. Similarly, it took city years of cash injection to assert themselves. Money is a factor, but you can't really buy titles.
I disagree with the Newcastle and Blackburn statements as well. He didn't wreck them Kenny took a team that was newly promoted to a fourth, second and first place finish in the league— in that order. Yes he had money, but money doesn't always translate to success. Blackburn fell apart when he was no longer manager, and they destroyed the house that Kenny built, not the other way around.
Newcastle have never REALLY been the big club they think they are, and they have never really had success with anyone. They haven't won a title since the twenties or a trophy at all since the fifties, even in Shearer's glory days. He didn't set the world alight there, but I'm not really surprised. A failure, yes, but certainly no bigger than Rafa's failure at Inter.
Kenny didn't come back for money. He could have left many times as a player if that's what it was. He's at home with Liverpool, and that's all that motivates him to keep coming back. He loves the club and the supporters, and if you think otherwise, I say you are gravely mistaken.
