who's better, Skrtel or Agger? I always thought Agger was the more composed one.
Agger is smarter and better with the ball, Skrtel is great at taming forwards. And Skrtel is only as smart as the guy next to him. If he's playing with someone, who can instruct him, he tends to do very well. If, however, his partner (or the keeper) can't organize the defence, Skrtel is a headless chicken. At least that's how our NT conceded most goals, as we have two good markers, but no one with brains.
I'd settle for any of them, oh and Skrtel can play as a LB too. While Agger have a stunning powerful right foot IIRC.
Skrtel at LB? I've never seen him play there, I personally think he's too clumsy to play as a fullback.
Agger is definitely better than Skrtel.
Depends on what you want. As a partner for Chiellini, definitely Agger. Though the idea of having two beasts as CBs is intriguing, to say the least. They would probably concede more goals, but would be much more fun to watch, that's for sure.
