The striker, now 35, has joined as a free agent from Shandong Luneng.
“I'm positive for the season, the position is difficult, but we don't have to feel sorry for ourselves," he said.
“We will try to turn things around and I'm a guy who likes pressure.
“I had several calls to resume after China, but Parma showed me more desire, not need. I had unfinished business here and I'm proud, I think I have to give more to this place."
