A route that has worked for Brazilians in recent years is from Brazil to an Eastern European team before moving to a big club providing they do well in Europe initially.
Going straight to a big club hasn't worked out too well lately with the exception of Neymar. Pato looked like a world beater at one point and even early on with Milan but the lifestyle and injuries curtailed his career.
Douglas Costa and Willian were both rated in Brazil and went to Shakhtar and developed their game before moving to Bayern and Chelsea respectively where they are doing very well. Coutinho struggled at Inter when he went there apart from a few good games, luckily he has managed to resurrect his career somewhat at Liverpool.
Gabriel Jesus would struggle to get in most of the big teams, just being a part time sub used when there are injuries. If he moved to Shakhtar, he would get regular football in a CL team, and would get used to European football. If he impresses, then I'm sure the big clubs would come knocking after 1-2 years.
