Well in the early 2000s we had Rivaldo and Ronaldo as goalscorer. But after late 2005 we haven't had a great striker.
Before that, Rivaldo, Ronaldo, Adriano get a year each or a bit more.
But yeah, it's horrible that a country like us hasn't produced a great striker for 5 years. Hopefully Pato and Neymar will live up to the hype.
