Fulham have tabled a £15 million bid for Newcastle striker Dwight Gayle after it became clear the player could be available, according to Press Association Sport.
The bid was received on Wednesday morning, hours after reports of the Championship club's interest in the 26-year-old emerged.
PA Sport reports that Newcastle value last season's 23-goal leading scorer at closer to £20m, although may yet be prepared to settle for somewhere between the two figures.
However, they will not consider doing business with Fulham or anyone else until they have a replacement lined up amid speculation that they have an interest in Liverpool's Divock Origi.
Manager Rafa Benitez is prepared to sell Gayle, whom he bought for £10m from Crystal Palace last summer, after a recent drop in form.
He has already drafted in Joselu in a £5m deal and has said he is looking for a different type of striker to complement the former Stoke man.
Benitez has been forced to rebuild for the Premier League on a budget at a time when other clubs are investing heavily, and is having to free up resources -- Emmanuel Riviere and Siem de Jong have left the club in the last week or so and Grant Hanley could soon join them -- to open the door for further incomings.
