I think you're all pretty much on the ball here, a very good thread.
Let me add something from a blog post I wrote in January this year:
<a class="postlink" href="http://mcfc-traut.blogspot.com/2010/01/mancinis-tactics-examined.html" onclick="window.open(this.href);return false;">http://mcfc-traut.blogspot.com/2010/01/ ... mined.html</a>
This is pretty much my take on how Mancini has played his teams for the majority of his management career. Inter is the best example of this by far!
I'll start off by showing an likely "ideal" line-up for Inter in the 2007/08 season:
Full backs: Chivu - Maicon
Both are very good defensively, but just as importantly they are excellent at attacking. Much like Chelsea under Ancelotti now. We don't have full backs like this, we've got defensive full backs who's not good enough at attacking and attacking full backs who aren't solid enough defensively.
Centre halfs: Cordoba - Materazzi
Classic Italian line up. One athletic and fast, one solid and dependable. Arguably we could have this with all our players fit.
Midfielders: Vieira - Cambiasso - Zanetti
This is in my opinion the crucial reason (along with the next player I'll cover) WHY Mancini can't play his preferred formation at the moment. Cambiasso is of course the destroyer who's main job is to tackle and win the ball. De Jong could be our answer. Vieira is pretty much the complete player who's excellent at tackling, great at passing and bombs forward a lot. Of course we've signed him now, but can he still perform this role? Can Barry perform this role? Zanetti was pretty much the (slightly defensive) engine room, the all-rounder. Barry, De Jong or even Zabaleta might be able to perform this role.
Attacking Midfielder: Stankovic
This is the crucial link-up between midfield and attack. Possibly the most important position on the pitch. A player who has huge creative freedom and is expected to make clever passes if the game stalls. With this position, it's merely a bonus if he helps out defensively, that's not his role.
Strikers: Ibrahimovic - Julio Cruz
Ibra is of course a tall and pretty much complete striker (people think he's "just" a target-man which very wrong), which very few clubs have! Sits quite deep and is very technically gifted. Although Tevez isn't tall he can actually head the ball. Apart from his height he fits the bill perfectly. Cruz is the tall striker that held up the ball but also scored a fair bit. In other words; Adebayor when he's at the top of this game.
