The Blues defender has called upon the Belgians to follow his compatriot and commit their futures to the Stamford Bridge club
David Luiz believes that his 'fantastic friend' Willian loves Chelsea and will not be leaving the club, but is less sure about the futures of Thibaut Courtois and Eden Hazard.
The trio have all been touted for potential exits from the club over the summer, with Barcelona pursuing Willian in a £60 million ($78m) move before eventually signing Malcom instead, while Courtois and Hazard have both had continued links with Real Madrid.
The transfer window closes on Thursday for English clubs, representing a last chance for the Blues to replace any players who may potentially be on the move.
