Estevao fears he won't receive enough playing time at Chelsea under Xabi Alonso.
According to ESPN Brasil, the Brazilian winger has started to worry about his role in the team after the early matches of the season.
Estevao prefers to operate closer to the centre of attack; however, he faces tough competition from Cole Palmer and Morgan Rogers for that spot.
Another option is to play on the right flank, where Xabi Alonso deploys Pedro Neto. Yet, Estevao doesn't consider this position to be ideal for himself. Reports suggest he is concerned that bulking up for regular play on this side could hamper his speed and agility.
At this stage, the situation isn't a conflict with the club or manager. Estevao remains happy at Chelsea and wants to stay in London. However, if his playing time doesn't improve in the first half of the season, his stance may change.
