AC Milan vice-president Adriano Galliani was delighted with their winter market campaign.
Galliani was proud of their transfer work last month.
"I had never taken part in such an intense January transfer session," Galliani said.
"We sold eight players and brought in four. We did a lot and it seems as if we made the right choices. I'm very satisfied.
"We've changed the skin of Milan. We've understood that an era has come to an end. This is year one of a Milan which will do well."
