Unfortunately no. Palmeiras' forum is pretty active and I use google translate and then there is Youtube where the Brazilians are very active in the comments section. South American football has a very good coverage on Youtube, especially the individual highlights.
I definitely read it or listened on a podcast somewhere. I think it was the BBC South American football journalist Tim Vickery.
Estevao shouldn't really have any problems joining the first team, not sure on Paez as his best role is in the middle and doesn't tend to play well on the wings.
I wish Brazil call estevao for their Copa squad so it it easier to judge whether he is ready or not.
He is still a bit lightweight and if you look at any clips from Brazilian league you can see the physicality is far from the Prem. But in a years time a young body will gain muscle at a good rate. I am sure Chelsea will consult him about gym routines even before he joins.
Breakthrough came a bit too late for a Copa call up but definitely in line for one in their next round of internationals.
If Martinelli can make the jump, I'm quite confident Estevao will be fine considering he is a much better player than Martinelli was.
It all depend whether Estevao can handle the intensity and physicality of PL.
I see, hopefully he get a call up so I can see him outside Brazil league.
I also distinctly remember seeing si I,ar clips of Andrey Santos breaking through into the national side at areally young age and we were buying the next big thing. Yet all I see lately from esteemed Brazilian legends is how poor Brazilian football is currently.
Endrick managed the physical side ok but on the day was not a star on the ball. Yamal is no different to Endrick physically but yamal was dishing out a yellow card to a French player at the end of 90 tough minutes.
Maresca made a point right at the start when joining that he definitely wanted Santos and Angelo involved in preseason.
Apparently Endrick only completed one pass against Uruguay in 90 mins and it was the kick off in the first half
. Only thing I noticed during the match was that he would usually turn his man, use his body and then get fouled. Clever player but has a lot of areas to improve, particularly as you said with the ball. He was a lost boy. 
Just shows how big the step up is. Unrealistic to throw them in the deep end at that level and expect immediate impact (although noting that, and more club experience, some will point to Yamal Lamine).Apparently Endrick only completed one pass against Uruguay in 90 mins and it was the kick off in the first half
