Parma attacker Jonathan Biabiany says he's working his way back from a heart problem.

Biabiany has replied to a fan's questions on Twitter.

"The club can't tell you much, but unfortunately it is taking longer than expected. I'll only return when I am 100 per cent recovered," wrote Biabiany.

"I hope to play again this year, but the heart is a serious issue, not a thigh strain or a fractured ankle... but I am running fast towards recovery."
