im not too sure, might be just an idea to go straight 4-4-2 for this one start with quag, and prob krasic on the right to limit risk on losing pepe for the roma clash and give matri much needed rest, and i believe he too is also a booking away from suspension.
I edited your formation. That's my starting lineup and potential early subs if we get an early lead. krasic needs time now, esti is diong well, Vidal to get subbed off early if we are in control, early sub for Matri as well and if DP gets tired Quag to come in.
I'd even be fine with a Quag-DP partnership to start and just keep Matri on the bench.
I wouldnt mind seeing Krasic but was thinking it would be good to bring him on later in the game when we are like 2-0 up to use his pace destroy them on the counters. Quag for Matri too later in the game would be good and maybe Elia but im sure Pazienza will come on at some point and maybe Giach.
