I don't understand why people are writing off Inter completely. They have at least the POTENTIAL to challenge quite significantly.
An attack consisting of Sneijder, Coutinho, Alvarez, Milito, Palacio and Cassano will be a force to be reckoned with - regardless of how sperglords feel about the latter two.
Midfield is kinda weak but Guarin can be good for them this season and Cambiasso might have a season of top-level football left in him. Mudingay is solid and completely unspectacular but a decent player nontheless.
Decent left and right backs in Nagatomo, Maicon and Jonathan. A mixture of youth (Ranocchia, Juan), experience (Samuel, Chivu) and a solid purchase in Silvestre for the central defense.
Add a good keeper in Handanovic and I think they will be our main rivals this year with Milan looking very thin, Roma having a great attack and like zero defenders, Udinese probably not bouncing back from these sales, Lazio being average and Napoli not a championship side.
I think we'll see 1. Juve, 2. Inter, 3. Napoli, 4. Milan, 5. Roma, 6. Udinese/Lazio.
