Despite signing Nemanja Matic in the summer, it seems United want another person in that position for next season. And Dier is their man of choice.
But it would take a massive fee in excess of £50 million for Spurs to even consider selling their English asset.
Dier was open to the move in the summer, and he would want to make the switch to United if a fee is agreed.
But he will not push for a move, and that will work against United in this pursuit.
