FOUR breakout stars for Chelsea next season

Oscar

While Oscar has already enjoyed two fairly productive seasons since joining Chelsea from Internacional prior to the 2012-13 season, the 22-year-old Brazilian native is poised to take the next step as one of the top wingers in the world. Mourinho typically deploys the left-footed playmaker on the left wing or just behind the striker.

Wherever he lines up, his production should be aided by the arrival of Costa, the type of consistent goal-scoring threat up top that Chelsea lacked last season. This should allow Oscar to use his superior dribbling and short passing skills to fit the ball into tight windows while also feeding off of the likes of Fabregas and Eden Hazard to form one of the top attacking units in the Premier League.
