Oscar accepts he may have to change his game to succeed at Chelsea.

The former Internacional midfielder could make his debut today against Wigan Athletic.

"In Brazil there is a different type of football, but I think I am seen as an elegant type of ball player, who is creating for another people. I may need to change a little bit over here, but I see myself as that sort of a player who can hopefully make a difference to the team," he told chelseafc.com.
