Chelsea coach Maresca talked about new aid Estewan in an interview, and said that for a young Brazilian player, it is very important to make him happy.
Maresca said: "I first met Estewan when he was a very good player when he was in the Club World Cup against Palmeiras. He was still young and always smiled happily. This is also a typical Brazilian character, and we want to keep him happy.
"For Estewan, we need to pay more attention than other new players because he comes from a very far away and is very young. So we need to be careful not to put too much pressure on him, make him feel happy, and give him enough time to adapt.
"Estewan certainly needs to adapt to the team. I hope we can give him enough playing time. There is no doubt that he is a very talented player. He can be competent in any position and has outstanding strength. In my opinion, Estewan's position is similar to Palmer, which can play both on the wing and on the middle. Estewan can adapt to the five offensive positions of our team."
