Candreva spent last season at Juventus and insists he is happy with another temporary switch.
"When news came through of negotiations with Parma, I didn't want to know about the other options," he explained.
"There wasn't long to go before the deadline and I immediately gave the all-clear. This is a great squad and proved it by beating Brescia in the season opener.
"There are some wonderful players and a great Coach, so I hope to get in shape as soon as possible and can't wait to start my new adventure with Parma."
