chiellini at left back and zambro pushed up in nedveds left role is a good idea. playing nedved alongside emerson in central midfield does give more offensiveness overall.
realistically what juve needs is a player with characteristics like Scholes for example. If you play with a playmaker, you need to change formation. however, if you as Lazio and United did in the late 90's..ie. Veron for lazio and scholes for united, then you dont have to change formation.
We see Maresca at Fiorentina scoring quite a few goals. He would be the perfect type of player to get. Can Olivera do what he does? i think he can but it would take at least a half season for him to really adapt well, something which Capello wont agree on doing.
Stuart, Nedved scored more when behind, but once again, we relied on his style of play too much.
With Nedved missing now through injury, it would be good to see what Capello tries. Surely Olivera must step in and take his place. Or even better, maybe Olivera and Kapo can both play at the same time to try that out.
