Vidic, Terry and Silva are clearly the top 3, if you use them correctly. I don't rate Chiellini that highly, but Kompany, Hummels or Pepe above Boateng is a fecking joke and both Varane and Benatia should be nowhere near all the others on that list.
Kompany > Boateng for me, Hummels/Pepe I think it's a slim margin but I can see how you would put Boateng over them which is fine by me. Nothing over the top here.
Pepe is a better CB than Ramos. Pepe is a lot better than Varane. Varane has potential but he hasn't shown anything that counts as a great season. Shouldn't be close to Pepe. Pepe is similar to Terry really. Their style that is. Pepe is quicker. Terry better in the air.
Even after that list I still consider him a top 5. You basically did the same. 5-8th is still top 5.
Pepe isn't a better CB than Ramos, very different types of CBs and Pepe may be a better stopper but I'd take Ramos over him to my team any day. Ramos offers leadership, better decision making, and a lot more on the ball. Plus, he's less risky in the voter's minds.
I've put Pepe over Varane by the way..
And no, top 5 isn't really like putting him 5-8th.
Surely Kompany is better than you rated!
Edit: My rating of players you mentioned...
Silva, Vidic, Terry
Kompany, Ramos, Pepe, Boateng
Hummels, Chiellini
Varane, Godin
I find the Kompany thing a bit odd, I personally always felt he's being overrated. Never got a real grip of leading ManC in the CL and I hold it against him. Maybe he's just better at defending against the big and strong strikers and not the fast ones, maybe it's just that he's not as good against teams who play on the ground..
I'd never rate him over Ramos, not sure he's above Chiellini either(who I find overrated often)
