Oscar has claimed that every player will try to impress new Chelsea manager Antonio Conte when he arrives at Stamford Bridge in the summer.
The 46-year-old, who recently agreed a three-year contract with the Premier League club, will take charge of the Blues when his spell as Italy boss comes to an end after Euro 2016.
Conte is likely to make changes to the team when he joins the club, and Oscar has urged everyone to be at their "best".
"I try to play my best for Chelsea but it's not just me, the whole team will try to win games to impress the new coach ahead of next season," Oscar told the club's official website.
Chelsea are currently 10th in the Premier League table with six games left to play.
