The Sicilians are haunted by the spectre of relegation from Serie A, but Coach Walter Zenga has promised that they will fight to the death as they look for a ticket to a their first Cup Final.
Roma also have League business on their mind with their Scudetto hopes resting on favourable results this weekend.
The holders are looking to book their fourth consecutive Final meeting against Inter, knowing that this year’s one-off decider will be played at their Stadio Olimpico.

A half-fit Daniele De Rossi is starting alongside Alberto Aquilani and Matteo Brighi, while Amantino Mancini starts on the bench.
