Felipe had his contract terminated over unpaid wages.
"At Parma we tried," Felipe told Inter Channel. "My former teammates still are. I was there for a year and a half.
"It's a delicate situation, I chose to terminate my deal, as did [Antonio] Cassano. I couldn't live well with what was happening.
"Others are still struggling and they're working to ensure things like this don't happen elsewhere. It's really difficult to live with."
