if bonucci has solid fullbacks in the team, he will be able to mature more quickly and positively. THIS season much will depend on his development. Last season he had excuses, of far too often having to play CB and RB. Similar with Giorgio. If Ziegler can take away much, if not all of the LB duties, which CHiellini HAD to add to his own CB duties, for 70% of last season, then he will also seem far better. With Lichstenier and Ziegler, also some more talent on the ball and capability to retain the ball in the midfield and attack, less pressure constantly weighing down on the defence as a whole...with Buffon back in form also...That defence could be far better than mediocre. In fact, i like the look of it...Who knows who can click well together??? Impossible to say. but Lich and Ziegler, are definite upgrades to Grosso/de ceglie and Motta. That in itself is work well done...especially when fullbacks, of a decent quality, are some of the rarest players to find.
