AC Milan boss Massimiliano Allegri understands Pippo Inzaghi's frustrations.

For victory over Palermo, Inzaghi could not even find a spot on the bench at San Siro.

"Everyone will be useful for this Milan. I had to make choices, the same way I did last season, for the good of Milan. Sometimes I get the decisions right, sometimes wrong, but I understand those who are sent to the stands are upset. They are professionals and understand the situation," said Allegri.
