Best defender of this generation is between Godin and Chiellini. Thiago Silva used to be good in Milan, but since he changed to PSG and face zero competition in the league he has declined, no where near to be considered the best. Regarding Ramos and Pique, I dont think they should be considered in the discussion, yeah they have won the UCL, Euro and World Cup but neither Barca, Madrid or Spain is admired because of their defense. Ramos figure has been highlighted since the goal against atletico in the final but if you watch la liga you’ll see how many times he makes silly mistakes.
