Inter Milan keeper Viviano determined to fight back from knee injury
He was set to join Genoa in August, but ligament damage sustained last week means he'll be out of action until 2012.
"I was certainly feeling better before the injury, although I'm happy that the operation went well," he told Sky Sport Italia.
"The next few months are going to be very difficult for me. I hope that I can get back to action sooner than the six months mentioned."
