Antonio Conte uses the example of his famed defence at Juventus to illustrate how David Luiz can fulfil his potential and become one of the best centre-backs in the world.
Conte insists the famed Juve trio of Andrea Barzagli, Leonardo Bonucci and Giorgio Chiellini - who also line up together for Italy - were ordinary players when he arrived in Turin in 2011.
Luiz is prone to losing concentration and taking some unnecessary risks, but Conte intends to iron out his shortcomings through hard work.
"It's important to remember when I started at Juventus, with Chiellini, Bonucci and Barzagli, the defence of Juventus had been conceding a lot of goals," Serie A title-winning former Juventus boss Conte said.
