There may be a slight problem with him taking the number 10 spot at Chelsea, however, due to a certain Cole Palmer.
Palmer already has 11 goals and six assists this season, so there maybe a slight headache for Enzo Maresca next season.
There won't be any animosity between the pair it seems.
The 'Messinho' has also been in contact with numerous squad members ahead of his arrival.
The 17-year-old also said: "Thiago Silva told me after our game that Chelsea is top! He told me they're waiting for me with open arms".
"Cole Palmer talks to me on Instagram… and also Reece James said if I need anything let him know.
"I really like the Cole Palmer cold celebration!
"I used that since I signed for Chelsea… we exchanged an idea, I spoke to Cole on Instagram about it! I'm happy to have this contact with him".
Chelsea reportedly discussed with Estevao and his agents about playing as 10 even before they signed him.
Estevao has been spotted emulating Palmer's 'cold' celebration before, rubbing his arms and puffing out his cheeks.
After one goal for Palmeiras, Estevao shared an image of him doing the 'cold Palmer' celebration on Instagram, and Cole Palmer loved it.
Palmer shared the image, with the simple caption: "Soon," accompanied by a winking emoji.
