Boasting the attacking prowess of Fernando Torres, Eden Hazard and Juan Mata, Chelsea have had no problems finding the back of the net this season. However, the Blues defence have been less than impressive, with Luiz appearing particularly susceptible in the heart of the Chelsea rear-guard.
The Brazilian was found lacking during the team's recent Premier League fixture against Manchester United, scoring an own goal before allowing Red Devils striker Robin van Persie to put in his team's second.
With John Terry set to return from suspension, there have been calls for Di Matteo to bench Luiz in favour of playing the Blues skipper alongside Gary Cahill. However, the Italian dismissed such suggestions and indicated that Luiz's contributions outshoned his mistakes.
"You need to see both sides, on one hand we have a fantastic player that can decide games for you and on the other hand you have to take into account that everybody can make mistakes," Di Matteo explained to the Fulham & Hammersmith Chronicle.
"But we want our defenders to play and be involved when we attack so I know more focus is put on the mistakes. But he scored a fantastic free-kick against Nordsjaelland and other important goals for us."
Di Matteo also indicated that he would not be advising the former Benfica man to change his style of play.
"You need to be able to take the best out of the players and I would never take his qualities or restrict qualities that a player had. He is a fantastic player for us," Di Matteo said.
"We are working on the fact that in certain moments maybe its better to play simple but he is a player with great qualities that has decided many games for us as well."
