If Heinze's suspended too, then they have bad problems in defense.
With Juan, Burdisso, Rosi, Kjaer and Heinze injured/suspended, the only ones left are Cicinho (RB), J. Angel (LB), Cassetti (RB), Taddei (winger forced to play LB) and Loic Nego (RB). They'll be forced to play two classical full backs at CB. Now that's already a huge advantage because fullbacks will definitely struggle with the positioning and with following the movement of Matri.
