Seven,
I like your exaggeration.

.
But I totally agree, I havent seen much of Kompany but on the occasions that I have seen him - What a talent! Big long legs, good footballing brain, and decent speed, and maturity beyond his age, he kind of reminds me of Nesta when the latter first broke through Lazio defence.
Mark 77,
Your list of CBs are great, but every year some players have break-through year so never buy a young promising star for the future IMO unless he is a
real deal or ready to contribute. For that reason I would rule out Julien Rodriguez (I dont really rate him anyway :dontcare

, Kroldrup (One more good year in Udine will convince me), King and Juan off the list.
Out of the list, Andrade (Top 5 CB IMO but hasnt he joined Real yet?), Gallas, Cordova and Chivu are established top-not defender that we should persue and Kompany is a cant miss talent. Bonera, Milito, Marquez, Squillaci are interesting players that can contribute.
