Newcastle United are hoping to gain as much as £40million from selling the likes of Moussa Sissoko, Georginio Wijnaldum, Daryl Janmaat and Andros Townsend, reports the Telegraph.
Newcastle are expected to be busy in the summer transfer window following their relegation from the Premier League.
Manager Rafa Benitez is likely to try to mould the squad to better suit what many are predicting will be a tough Championship campaign next year.
How much work that will be needed is however dependent on who leaves the club, with several star players already reportedly eyeing exits.
They are hoping to make good money on the quartet though, with the same report claiming they are hoping for as much as £40million should all four decide be moved on.
Luckily for Benitez, owner Mike Ashley has instructed managing director Lee Charnley that the Spaniard is allowed to reinvest the money from any player sales.
