OFFICIAL: Chelsea complete signing of David Luiz

Chelsea have confirmed that the defender has signed a three-year deal with the Blues, just two years after he left for Paris St-Germain.
The defender played 142 games for Chelsea in his previous spell at Stamford Bridge and won the Champions League and the FA Cup with the Blues, although he never won a Premier League title.
The Brazilian enjoyed a decorated couple of seasons at PSG, winning a total of eight trophies in his two years in the French capital.
"I always had a wonderful relationship with the fans and I am looking forward to wearing the blue shirt at Stamford Bridge once again," Luiz told the club's official website.
