I am from Brazil and I'd recommend:
Neymar - Santos
Marquinhos - Internacional
Carlos Eduardo - Hoffeinheim
Sandro - Internacional
Taison - Internacional
Giuliano - Internacional
Dodo - Corinthians
Matias defederico - Corinthians
Rafael Toloi - Goias
Felipe Coutinho - Vasco / Inter Milan
None there that was transfer for £1m or less.
