Fresh from their thrilling 3-3 draw with Juventus in midweek, the southern Italian giants now prepare for the visit of a struggling Giallorossi outfit in need of points.Unsurprisingly, coach Walter Mazzarri has his eyes firmly set on Tuesday\'s crunch Champions League encounter against Villarreal, and therefore it is likely he will field a much-changed XI on Saturday. An estimated six alterations should take effect from the side that drew 3-3 with Juventus on Wednesday. Key performers Paolo Cannavaro, Hugo Campagnaro, Juan Zuniga, Walter Gargano, Marek Hamsik and Edinson Cavani are all likely to be sacrificed in favour of Federico Fernandez, Ignacio Fideleff, Andrea Dossena, Blerim Dzemaili and Mario Santana. Ezequiel Lavezzi is also set to lead the line, with his fellow countryman Santana ready to take the reins alongside midweek hero Goran Pandev in the hole. Meanwhile for the visitors, they too are lining up several alterations from the disappointing 1-0 loss to Catania last week. Out of the side go Davide Brivio, Juan Cuadrado, Andrea Bertolacci and the injured Ruben Olivera, with Stefano Ferrario, Djamel Mesbah, Carlos Grossmuller and Cristian Pasquato coming in. A tactical switch to a 5-3-2 formation is also expected. However, there isn\'t such luck for Edward Ofere, Guillermo Giacomazzi, Moris Carrozzieri, Souleymane Diamoutene and David Di Michele, who all face further spells on the treatment table
