World Cup player profile: OscarOscar impressed at the Confederations Cup last year
Caps [goals]: 29 
The Brazilian started his career with Internacional and São Paulo at home, before moving to Europe with Chelsea in 2012.
Why has he been selected?
The 22-year-old was an important member of the Brazil squad that won the Confederations Cup in 2013. He was also part of the group which reached the final at the Olympic Games in London the previous year.
How has he played this season?
He had an impressive season with Chelsea, with the team finishing third in the English Premier League and making it to the semi-final stage of the Champions League. His understanding with the likes of fellow Brazilian Willian and Eden Hazard have made him an effective presence in the Chelsea attack.
What will his role be in Brazil?
Oscar has played his way into Luiz Felipe Scolari’s starting XI and will be integral to the coach’s plans. Brazil will be hoping that the player’s not suffering from fatigue after so many matches this season. If he comes through fitness tests unscathed at the end of the month, there is no doubt that he will be deployed as one of Scolari’s three behind Fred throughout the tournament.
