Luca Castellazzi is on stand-by should goalkeeper Julio Cesar be ruled out of tonight’s Champions League game against Marseille.
The Brazilian international, according to the Corriere dello Sport, picked up a back problem in training on Tuesday.
Should the South American not pass a fitness test then he will be replaced in the nets by the 36-year-old.
Former Samp man Castellazzi has already played in two Champions League games and three Serie A ties so far this term.
