Antonio Conte says David Luiz could face a lengthy spell out of the Chelsea squad after dropping the defender for Sunday's Premier League win over Manchester United.
Luiz was left out of the squad entirely, with Conte picking Andreas Christensen in his back three and naming only 17-year-old Ethan Ampadu as a defensive option on the bench.
The risk paid off as Chelsea won 1-0, and after the game Conte praised the players who came in while warning Luiz he has to work better as a team player if he is to get back in the starting 11.
