Marco Borriello struck both goals in the 2-0 win, but Ronie was outstanding in midfield for the victors.
"Ronaldinho is doing very well, this tactical setup, with the Brazilian playing behind Alexandre Pato, who plays wide on the right, is working well. The team plays good football," said Galliani.
The Milan vice-president also admitted they needed to find ways to bring fans back to the San Siro.
"It's a shame about the drop in support, it is not justified, but we accept this position even if the statistics are troubling. We will do everything possible to recover our fans," he added.
