He's good and has great potential but hardly worth banking on as our mean strike weapon next season. The problem these days is that these Brazillians get so hyped early on and then are only expected to go directly to top clubs. It's not like the Romarios, Ronaldos, Rivaldos and Ronaldinhos (that's a lot of fucking R's) that went through mid tier european clubs first before they were picked up by the big teams.
Neymar, Damiao and Ganso haven't done shit outside the mickey mouse leagues yet the only clubs that are realistically on the table are powerhouses or nouveau riche (heh) ones.
