The Blues boss has lauded his summer signing over his performances and also insisted that Willian and Cesc Fabregas remain important players
David Luiz has been playing through the pain barrier and is still suffering with the knee injury he picked up against Manchester City in December.
The 30-year-old centre-back made his return to Chelsea in the summer in a deadline-day £32 million move from Paris Saint-Germain and has proved his critics wrong with a number of impressive performances.
And Conte has explained at a press conference at Cobham Training Centre on Friday that Luiz is still playing through pain but that he is a warrior that is able to cope with it.
