You mix apples and pears. My support for Benitez in JR's thread is about what is a sensible model, and how we as a club can get better. Having a very expensive player, who struggles to get his body in top form in the world's most intensive league for a team that ends up in the middle of the table, does not make sense.
From the posts it is clear that I have not actively participated in the polarized debate, except for a few posts where I have pointed out that it is too early to conclude, and that Benitez is known for being a coach who breathes football and is good at organizing teams. Ancelotti is in many ways the opposite of Benitez.
I have also mentioned Nils Arne Eggen. I reckon you've heard of him, and he recently turned 80. He has received UEFA's highest honorary award, and is classified together with coaches such as Alex Fergusen, Rinus Michels, etc. Perhaps one of the best coaches of all time. At least the top 10.
