I've been doing a bit of research on young strikers making a name for themselves in South America, and a lot of the same players keep cropping up. Whilst it's the case that many young talented players in that continent are snapped up very quickly by European teams, some do stay in their native country a little longer - Neymar certainly springs to mind given how long he stayed at Santos before his big money move to Barca. This article sums up the candidates nicely - http://www.thestatszone.com/articles/five-strikers-making-waves-in-latin-america Any more to add to the list?
I still think Chala in Ecuador could do a job in Europe, but his time in Russia was always going to be tough.
