Jermain Defoe has received threats from Portsmouth fans angered by the prospect of him leaving the club, admitting: "Some of the calls have made me sick to my stomach."
The England striker looks increasingly likely to leave Fratton Park with Tottenham, Manchester City and even Juventus being linked with a move for him.
He told the Sunday Mirror: "I have absolutely no idea how they got hold of my number but some of the calls have made me sick to my stomach."
"I have reported it to officials at the club, but cannot accept that it is coming from people with a balanced state of mind.
"It has infuriated and upset my family and left me wondering what on earth possesses people to do things like that."
