Norwich City face a battle to keep hold of midfield pair James Maddison and Jacob Murphy.
The Mirror says the Championship club have already put a £30million price-tag on England Under-21 forward Maddison, who has scored 15 goals this term.
Premier League outfits Liverpool and Tottenham both want the 21-year-old, along with several other top-flight clubs.
The financial situation could also see them cash in on in-form winger Murphy, who scored his 10th of the season against Aston Villa last weekend in a brilliant Man of the Match display.
The 23-year-old's twin brother Jacob was sold to Newcastle last summer for £12m and Josh is attracting interest from Leicester, Bournemouth and Crystal Palace.
