Everton are leading the race for the £6million-rated England Under-21 star.
Nugent told The People: “Being a full international could price me out of a move. But I’ve only a year left on my contract so obviously it’s up to Preston to accept a bid.
“If they don’t, they will get no money at the end of the season.
“They know I’m not going to sign a new contract. The Premiership is where I need to be.”
