( CNN ) -- Serie A leaders AC Milan remain on course for a domestic double after reaching the quarterfinals of the Italian Cup with a 3-0 home win over Bari . Milan , with Antonio Cassano making his debut for the club , were always in control at the San Siro , and they now travel to Cassano 's former club Sampdoria -- with a place in the semifinals up for grabs . Zlatan Ibrahimovic continued his impressive recent form by opening the scoring for the home side in the 19th minute . And there was no way back for Bari once young German midfielder Alexander Merkel had doubled Milan 's advantage on the stroke of halftime . Man-of-the-match Robinho made the opening two goals before deservedly getting on the scoresheet himself midway through the second half , converting a pass from Merkel . The other quarterfinal ties will see Napoli entertain holders Inter Milan , Juventus play host to Roma and Palermo facing Parma .
