Chelsea and Atletico Madrid are at loggerheads over a fee for Filipe Luis.
The Blues are in search of a new left-back following the departure of Ashley Cole this summer.
However, negotiations between the two teams have reached deadlock.
Atleti are playing hardball and are demanding Jose Mourinho’s Blues must pay the full £19million value of the player’s buyout clause.
The Brazilian has made his position clear to his employers and has told them he wants to move to west London.
Chelsea have already signed Diego Costa from Diego Simeone’s Spanish champions this summer and Thibaut Courtois will return following a loan spell under the Argentine.
Fresh reports this morning also suggest Tiago could be set to return to Stamford Bridge on a free transfer and Mourinho could move for Atleti centre-back Miranda.
