AC Milan boss Max Allegri says they cannot afford to lose Antonio Cassano.
Cassano is unsettled at the Rossoneri.
Ibrahimovic misses the Trofeo Berlusconi with a sprained ankle, so Antonio Cassano will start against Juventus," said Allegri.
"At the moment he is our only available striker, is doing well and preparing to have a great season. He knows competition at Milan is fierce and he must always be ready to prove himself."
