There is real excitement among Blues fans about the 18-year-old, who arrived at Chelsea this week one year after the Blues signed him for an initial fee of £29million from Palmeiras.
Estevao starred for Palmeiras at the Club World Cup this summer and is regarded as one of the best young talents in world football.
The versatile forward, who is capable of playing wide or centrally, already has five caps for Brazil and scored 27 goals and recorded 15 assists in his 83 appearances for Palmeiras.
Estevao is one of the brightest young talents in world football
Estevao is viewed as one of the best young talents to come out of Brazil since Neymar, but Maresca is wary about putting too much pressure on him.
“We need to pay a little bit more attention, because first of all he’s from the other part of the world and also he’s very, very young,” he said. “So we need to pay attention.
“As I said, [he is] not under pressure, give him happiness, give him time, he needs to adapt. Hopefully we can give him minutes, so he’s even more happy. But for sure, he’s a talented player.

“For me, the biggest mistake we can do with him is to put him under pressure. He’s very young, he needs to adapt.
“I met him for the first time in the USA when we played against Palmeiras. He’s a fantastic player, he’s very young, he’s a happy boy. He’s always laughing, typical from a Brazilian guy, and we need to keep him happy.”
Estevao will hope to make his first appearance for Chelsea this week, with the Blues having two friendlies and Bayer Leverkusen on Friday and AC Milan on Sunday.
“He can play everywhere,” said Maresca. “He’s so good. For me, he’s like Cole [Palmer], in terms of - careful - he is like Cole in terms of his position.
“He can play outside, he can play inside, he can play everywhere. In our five attacking positions, for me, he can play everywhere.”
