Chelsea have reportedly agreed a £20m fee with Atletico Madrid for left-back Filipe Luis.
The Blues have been repeatedly linked with the Brazilian defender, and the Los Rojiblancos star's switch to Stamford Bridge is now imminent, according to the Daily Mail.
Despite Cesar Azpilicueta playing most of last season as a left-back, Blues boss Jose Mourinho has been keen to recruit after losing Ashley Cole on a free transfer.
The 28-year-old was part of the Atleti squad that won the La Liga title last term.
