Defending champion Juventus needed two late goals from substitutes for a 2-0 win over Napoli in a top-of-the-table clash Sunday to take control of the Italian league and extend its Serie A unbeaten streak to 47 matches.

Juventus have one foot in the Italian Cup final after Martin Caceres scored a brace to hand them a 2-1 win over AC Milan in the semi-final, first leg at the San Siro on Wednesday.

Martin Caceres, on loan to Sevilla from Barcelona, knows that his current side will need a fair share of good fortune if they are to prevail against his all-conquering parent club on Saturday.
