Leandro Damião - Internacional (Brazil)
Although he came off the bench to score a vital goal in the Final of the 2010 Libertadores, Damião was only a bit-part player that year for Inter. He didn't really make his name until last term, when a flurry of goals put him into contention for Brazil's number 9 shirt.
The news from the 2012 Libertadores is that his form last season was no fluke and he found the target six times before Inter were narrowly beaten by their compatriots Fluminese.
Even more encouraging was the evidence of his all-round improvement as a player. Very much a finisher, he was proficient in the air and with both feet but not especially comfortable linking the play. This year, however, his back-to-goal game has show massive improvement and a highlight of the competition for Inter was the relationship formed with attacking midfielder Oscar.
The quick, skilful exchanges between the pair give rise to the hope that the duo could form an important part of Brazil's Olympic side.
