The flamboyant Brazilian was a cult figure at Stamford Bridge in his first spell, but was known for some high profile errors as well as moments of brilliance.
Luiz is expected to make his second Chelsea debut in Sunday's trip to Swansea City in the Premier League. "This transfer market was very hard for us to reach our targets, but at the last minute, on the last day, there was this situation which was good for me and the club to improve the squad".
Former Chelsea coach Ray Wilkins has called David Luiz "a penalty just waiting to happen". We invested in David, and I'm very happy.
"David can improve in defensive situations, but I am very happy to have him here".
"He's a good guy, a positive guy for the changing room". I put my sweat into my players.
"But if you think that the players improve only by looking at them, it's impossible". I think that's the most important thing for me - not only to win, lose or draw.

Conte admits that signing Alonso and Luiz was necessary due to their depleted defensive resources, but is confident that the duo have definitely improved his squad at Stamford Bridge. I think David is a good player and he showed this in his career.
"Even when you are 32, 33 or 36 you can always improve".
Chelsea have made a B£6million profit on Luiz, who spent two years at PSG, and Conte believes they have re-signed a player capable of becoming one of the best defenders in the world. Also, I have a great responsibility to improve him in these aspects. "He has played at Chelsea before and will bring good personality to the team".
We'll soon have Thiago Silva back to full fitness too with the captain a near certainty to be back in the starting XI when he's 100%, he'll not rush him though, with Emery adding.
"Then, through the work, I think that now we are talking about three of the best defenders in the world when we talk about Chiellini, Bonucci and Barzagli".
