#2 Paulinho
A couple of years back, if you'd have suggested that Paulinho would star in a Barcelona team that went nigh-undefeated in the league, and then go on to play a pivotal role in Brazil's run to the quarters, you'd have been laughed out of the room. And they'd have been right to.
Languishing in China - (not according to him, though: "So I was going to play in China for Felipe Scolari? Does that sound so bad? I was happy about it, for real.") - he'd been signed up by Barcelona last summer after some impressive showings for Tite in the Qualifiers and during the World Cup he showed just why - his box-to-box presence a reminder that that particular art is not dead just yet.
His late-runs into the box caused all sorts of problems for opposition throughout the tournament - even for the Belgians, against whom he was unlucky that many of the balls fell agonisingly short, or behind, him.
