Tottenham Hotspur have allegedly threatened to block Gareth Bale's proposed move to Real Madrid should they fail to secure the services of Willian.
Spurs were lining up the Anzhi Makhachkala winger as a replacement for the Weshman, but Chelsea appear to have hijacked the deal with a late bid.
The North London club's chairman Daniel Levy is furious over Chelsea's pursuit of their target and is now considering slamming the brakes on Bale's £94m Real switch, according to the Daily Mail.
Willian appeared to be on the brink of joining Spurs at the beginning of the week, but is said to be in "advanced talks" with Chelsea.
