Semis, not quarterfinals (my prediction is for Russia to win the Q1 match against the Netherlands and lose the S1 match to Spain). But to be top scorer, being good in a single match is enough. David Villa was top scorer last time with a meagre 4, of which he scored three in a single match (incidentally, against Russia).
