AC Milan boss Max Allegri was delighted with victory over Viktoria Plzen.
The Rossoneri beat Viktoria Plzen 2-0 at San Siro with Ibra's penalty and Antonio Cassano scored the 2,000th Milan goal in the Silvio Berlusconi era, which began in 1986.
"It is an important victory to give consistency to what we did in Barcelona," the Coach told Sky Sport Italia.
"We alternated good things with not so good, but overall the win was deserved. Ibrahimovic is an important player and can give great physical presence to the side."
