I also don't like seeing Marchionni starting this match, but who knows, maybe it will be a great call at the end.
Many players give their best performances against one particular team. Grygera's doing that against Genoa, Trez is doing that against Empoli, Del Piero against Parma, Cruz against Juve, Seedorf against Juve etc.
Well, Milan are Marchionni's cup of team. 3 goals on 6 matches against Milan while he was playing for Parma (2 of them scored in that 3:4 defeat when he probably played the best match in his career).
He also scored a goal and played very well on that 45 minute friendly against Milan in the summer.
Am i being way too optimistic?
