The Tottenham Hotspur player is said to be attracting the interest of Manchester United.
The report claims Spurs have told Jose Mourinho's side that £50million will simply not be enough for the England international, who is allegedly seen as the heir apparent to Michael Carrick in the centre of United's midfield.
That said, if Tottenham do push the price closer to £55million or even £60million for the 23-year-old, it would go down as one of their chairman Daniel Levy's best ever pieces of business; up there with the world-record sale of Gareth Bale.
Dier signed for Tottenham from Sporting Lisbon for just £4million in 2014 (as reported by the BBC), and if Spurs sell him for a huge sum only three years later Levy will be laughing all the way to the bank.
When you consider the knockdown prices Spurs managed to sign the likes of Victor Wanyama and Dele Alli for, selling Dier is not beyond the realms of possibility.
After all, they have sufficient cover both in defence and in midfield and for that kind of money Tottenham manager Mauricio Pochettino could sufficiently strengthen in key areas.
Only time will tell if United are desperate enough to bid whatever it takes for Dier, but one man will be smiling the widest if a deal is struck, and that is Levy.
