Cole??Don't make me laugh. Abidal is a good aswell. Marcelo is good going forward,weak defending. Chiellini,I can't comment on him I've never seen him play.
There is, but I still wouldn't say that BAS is the best in the world. Not even the best in the PL. (That would probably be Enrique for me, although it is hard to judge defenders, especially fullbacks, unless you're watching them closely week-in, week-out).
Not gonna do a top 15 list (You can't compare positions) so I'll do 22 by position... Keepers: Casillas, Neuer Fullbacks: Lahm, Ramos, Chiellini (mainly a CB but shut up), Alves Centrebacks: Vidic, Pique, Thiago Silva, Kompany Midfield (too many types of midfielder to split this up): Xavi, Iniesta, Modric, Ozil, Silva, Pastore, Gotze, Yaya Toure Forwards: Messi, Ronaldo, Zlatan, Aguero
Because he's been brilliant for every team he's played for? His scoring records are consistently good, maybe bar Juventus, and he lets teams build attacks around him. It's brilliant seeing him be the heart of attacks, such a well rounded player. And as you've never seen Giorgio Chiellini play, I think it's safe to say you're not the most versed on Italian football.
