I dont know if they're undiscovered or if they'll play well in the Dutch league, but:
Check Cruzeiro (team) out. They've got a few awesome players in the team. Kerlon, Ramon, Guilherme, Wagner, Rafinha are all good.
Also, check out Fluminese. Again some cool players there. Particularly Thiago Neves.
Alan Kardec and Morais at Vasco.
Fernando Mineiro at Atletico Paranese is a good striker. Joao Carlos from the same team a future brilliant GK.
Obviously, you have Renato Augusto at Flamengo.
Palmeiras has some good players as well. Cant remember the names though.
Santos too. Check out Claudio Maldonado. He's an AWESOME DM!
Sao Paolo has a lot of great players too. Look them up!
