Thanks to injuries, it looks like Inter Milan have been forced into moving Javier Zanetti back to the back four, despite the fact that he's played so well in midfield over the last couple of years. Inter have been devastated by injuries at the back this season, and their makeshift selection could give Schalke hope. Ivan Cordoba is not totally fit and Marco Materazzi is a bit past it at this point, but both are on the bench in case of an emergency.
In the middle, Leonardo has selected what would appear to be a four man diamond midfield with Wesley Sneijder at the tip, supporting strikers Samuel Eto'o and the finally fit Diego Milito. Goran Pandev has been left on the bench. Here's the full lineup.
Inter Milan lineup (Projected 4-4-2 narrow diamond): Julio Cesar; Zanetti, Chivu, Ranocchia, Maicon; Thiago Motta, Cambiasso, Stankovic, Sneijder; Eto'o, Milito.
This lineup should match up favorably with Schalke in the middle and unfavorably out wide, as the German side are expected to play a flat 4-4-2.
