Three points for either side will massively help them in the fight against the drop.
With the bottom three in Serie A struggling for points and Brescia too failing, Cagliari have given themselves some breathing space even though they are 16th in the Serie A standings. With 17 points from 15 matches, the Sardinians are five points above the relegation zone and are, to some extent, looking safe at the moment.
The Isolani have been picking up wins at regular intervals especially against fellow strugglers and will attempt to do the same this weekend too. Roberto Donadoni's side went down 1-0 to Fiorentina in Florence in their last league encounter but prior to that they had won 3-2 against Lecce and defeated Brescia 2-1.
Cagliari have picked up three wins out of a possible seven in the league at home and will strive to add to their tally this weekend when they confront Catania at the Stadio Sant'Elia.
Catania must be smarting from their 3-1 defeat to Juventus at the Angelo Massimino last weekend. It was the Sicilians' first defeat at home in the league in a year and stationed them 14th in the Serie A standings.
The Etnei have mustered 18 points from 15 matches and are a solid six points above the dropzone. Catania commenced the 2010-11 campaign as one of the relegation-threatened sides but they are gradually inching towards mid-table security.
Catania, though, have yet to win on the road in the league this campaign and have collected just three points from a possible 21. However, encouragingly their last three away fixtures have resulted in draws with Sampdoria and Lazio.
Laner is injured and Astori is suspended.
Augustyn, Spolli and Mascara are injured and will miss the trip to Sardinia.
