Massimiliano Allegri\'s side welcome the Bianconeri on Saturday, knowing a victory over the visitors would send them temporarily to the summit of Serie A.For the home side, Philippe Mexes is set to start his first league game for the Rossoneri since signing from Roma in the summer, with Alessandro Nesta and Mario Yepes both ruled out through injury. The champions should also welcome back Antonio Nocerino after the former Palermo midfielder returned to full training following a thigh injury.However, Cristian Abbiati is unlikely to feature, with the 34-year-old still nursing the shoulder injury that has seen him miss Milan\'s last four fixtures, while Gianluca Zambrotta is also a doubt.The visitors will travel to Milan without veteran midfielder Simone Vergassola, with the former Sampdoria man still suffering from the muscle strain that has seen him out of action since late October. Cristian Del Grosso and Nicolas Belmonte are also unlikely to feature for the visitors.
