Ex-Chelsea manager and Dutch legend Ruud Gullit believes David Luiz is perfect for Chelsea’s 3-4-3 system.
“A lot of people questioned Chelsea’s decision to re-sign Brazil defender David Luiz from Paris Saint-Germain on transfer deadline day but he is proving to be the perfect fit for their 3-4-3 system,” Gullit told BBC Sports.
“I understand why there were doubts – while Blues manager Antonio Conte is known for his teams’ defensive discipline, Luiz’s problem is that sometimes he will switch off and he can be a little more complacent.
“At 29, he has not changed and he is still that same player who can make mistakes, but the formation Conte has used during their eight-game winning run allows him to play to his strengths because of the players he has got around him.
“In front of him, Chelsea’s defence is protected by N’Golo Kante and Nemanja Matic but the key for Luiz is that when Chelsea play three at the back, he does not have to mark anybody.
“Gary Cahill and Cesar Azpilicueta do that and do the dirty work for him.
“When Luiz plays in a four-man defence and he needs to mark, that can be a problem for him. In this 3-4-3 system, however, he is more of a sweeper and makes fewer challenges than Chelsea’s other defenders.
“That suits him more, firstly because he rarely finds himself in trouble so is not in danger of making a mistake and also because he is the player with the most freedom in that Chelsea team.
“Luiz can bring the ball out or play it forward and he uses it very well, which is so important when Chelsea look to break quickly.
“Playing him alongside Cahill and Azpilicueta means they have the ideal combination at the back.”
