Bologna host Palermo knowing that anything but a win could see them fall to the drop zone this weekend. Franco Colomba's side lost 2-1 at Roma in the last round and dropped to the last position of safety, level on nine points with third from bottom Livorno. Rossoblu striker Marco Di Vaio admitted his team wasted a good chance to claim three points against the Romans and hopes his team can make amends this weekend. "We should have punished Roma but we didn't," said Di Vaio. "It's a pity that we missed several goalscoring opportunities because we allowed Roma to escape unharmed." The Rossoblu have been boosted by the arrival of Ghana midfielder Stephan Appiah this week. Appiah could make his debut on Sunday.
