I think that the best equation for success is defense + offense. To win championships and titles, you MUST be great at both. It is very clear that Juve needs a new defense core, but lets not forget that our offense has not been up to par sometimes during the season. I think that Moggi should start helping the back line; bring in 2 young center backs and a new RB. That should cover the defense. Now, the midfield must be revamped as well. Our side lacks creativity, it is very clear.
To win championships, yes you need a good defense, but you also need creativity in attack, which we do not have. Milan, Monaco, Deportivo, and Porto all have creative playmakers, and that along with a strong defense is the reason why they are so succesful. Milan with players like Kaka and Pirlo, Monaco with Giuly and Rothen, Depor with Valeron and Sergio, and Porto with Deco and Maniche. As you see, each side has at LEAST two creative midfielders. Juve? Our main source of creative skills in the midfield come from a player who is not even a natural playmaker, Nedved. Neddy is great and all, but he doesn't even have half of Kaka's creativity. And on top of that, Appiah and Tacchinardi have no sense of passing skills at all. It was ever so apparent in the Depor matches that our attack sucks too. I think if we want to win something next year, Moggi will have to find a true playmaker. If that means selling Nedved, so be it. Success now a days calls for yes, a good defense, but also attacking flair. So a change in midfield must occur, or I will be saying "told you so" at this time next year.
