Chelsea have re-opened talks with Atletico Madrid over their move to sign Filipe Luis. The left-back is viewed as a priority signing by boss Jose Mourinho but the Blues have so far been frustrated in their attempts to sign Luis. Target: Filipe Luis impressed for Atletico last season and is keen to make the move to Chelsea . Almost: Luis, not picked in Brazil's World Cup squad, is closing in on a switch to Stamford Bridge . The 28-year-old has a release clause, understood to be in the region of £20million, that Chelsea have been reluctant to trigger. But Stamford Bridge chiefs are back in talks with their Spanish counterparts with a view to concluding the protracted transfer in the coming days. Strengthening at left-back is a major concern for Mourinho going into the new season. Long-term left-back Ashley Cole has left the club for Roma after his contract expired. Cole was kept out of the side last season by Cesar Azpilicueta, but the Spaniard is a right-back by trade. On his way: the full-back could follow striker Diego Costa (above) to Stamford Bridge next season . VIDEO Chelsea reach Costa agreement .
