Tottenham Hotspur officials are reportedly fearing a potential January battle for Luka Modric.
The Croatian was the subject of intense transfer speculation this summer, with Chelsea tabling a handful of offers for the player, including a £40 million bid on the penultimate day of the transfer window, and Manchester United also linked.
Daniel Levy vowed to keep hold of the player, and stayed true to his word alongside Harry Redknapp at White Hart Lane despite a written transfer request from the player.
However, The Metro claims Manchester United are now being feared as suitors for the player in the New Year.
The Red Devils were also linked with the player this summer, as well as Wesley Sneijder, with Sir Alex Ferguson keen to add a playmaker to the ranks at Manchester United following the retirement of Paul Scholes.
Ferguson spent well in the early stages of the window, bringing Ashley Young, David de Gea and Phil Jones to Old Trafford, but failed in their well-publicised pursuit of the Dutchman after he confirmed talks between Inter Milan and Manchester United took place.
A potential Manchester United move could hinge on the attitude of Modric in the coming months, but the transfer saga is certain to continue to run post-christmas.
