Portsmouth boss Harry Redknapp has admitted David Nugent could leave after starting only two league games following a £6m move from Preston.
Nugent signed for Portsmouth in July for £6m
Nugent, 22, scored his first goal for Pompey in the 3-0 win against Leeds in the Carling Cup on Tuesday.
But Redknapp confirmed he could be on the move, with Derby interested.
He said: "Sometimes when you are trying
to raise money you have to sell someone you don't really want to sell. That could be David but it could be others."
Redknapp added: "What we need is somebody who can get us 15 to 20 goals a season and if we can do some good business and improve the team we will."
Pompey signed Nugent for £6m in July from Preston, but after starting the first two games of the season, he was on the bench for the last two.
Nugent is now a target for Derby where he would link up with Billy Davies, his former boss at Preston.
Redknapp said: "He's a young player and obviously he wants to play but at the moment Kanu has been absolutely brilliant, John Utaka's a threat and Benjani does well.
Newspaper reports suggest Redknapp wants to sign £12m-rated Bolton striker Nicolas Anelka - but he may have to sell before he buys.
