Manchester United already had a bid for Eric Dier turned down by Tottenham, the north London club adamant the midfielder wasn't for sale. Since then, Jose Mourinho had moved on to other targets, including Chelsea man Nemanja Matic.
However, with the Red Devils poised to take Lukaku from under Conte's nose, it seems the Blues would not be willing to sell the Serbian midfielder.
Jose Mourinho is prepared to test Spurs' resolve and bid £50 million for Eric Dier, who was always the manager's preferred option to occupy his team's midfield.
Dier himself is open to a move after seeing defensive midfielder Victor Wanyama squeeze the England international out of Tottenham's midfield and into the back three.
