Former World Cup legend Zico believes Chelsea boss Jose Mourinho could have handled Oscar better than he has done this season.
He told The Guardian: "I was a bit surprised that Jose Mourinho did not use Oscar more often this season, especially when he has a player like Eden Hazard in his squad.
"The two together are a handful. Hazard is exciting to watch. I like the way he takes on his markers."
He went onto hail Oscar's potential to be Brazil's game-changer, describing him as every bit as important to the Selecao as Barcelona forward Neymar.
Oscar, 22, has eight goals in 28 games for Brazil's senior side, the same number of goals as he scored for Chelsea in 33 games this season.
Of these goals however for Chelsea, six came before mid-January, with the remaining two coming in the 6-0 demolition of Arsenal in March.
In his 33 games in the Premier League, Oscar played for 90 minutes in just eight of them, partly due to the plethora of options Chelsea have at their disposal on the bench.
There is bigger expectation in Brazil on Oscar than at Chelsea, and he has a lot to live up to at the World Cup. If he can step up and deliver, then he may give Mourinho even more food for thought ahead of next season.
