World Cup player profile: David Luiz
Name: David Luiz
Position: Centre back
Caps [goals]: 34 
David Luiz has spent the past seven years in Europe, moving to Benfica in 2007 from Vitoria and then transferring to English side Chelsea in 2011 for a fee in the region of €25 million. In his time at Stamford Bridge, he has helped the club to win the Champions League in 2012 as well as the Europa League the following season.
Why has he been selected?
Luiz is one of head coach Luiz Felipe Scolari's most trusted options at the back, as well as providing cover if necessary in a defensive midfield capacity, although it would appear that the boss has others in mind there. A bubbly character, he fits the profile of the rest of the squad perfectly.
How has he played this season?
Helped Chelsea to the semi-finals of the Champions League in Jose Mourinho's first term back at the club, as well as representing Brazil 17 times since the turn of last year; has long been linked with a move to Spanish giants Barcelona.
What will his role be in Brazil?
A certainty to start the first game against Croatia alongside captain Thiago Silva, Luiz would be expected to play a full part in Brazil's entire campaign.
