Has to be an Argentinian for top goal scorer - have you seen their group? They'll probably bag about ten goals against Iran alone - so Aguero for me for top goalscorer (Messi doesn't seem to bang them in as often for Argentina as he does for Barca, plays in a slightly deeper role)
Difficult to pick a winner - Would love to see a European win it, but fancy Uraguay as an outsider - they were close in South Africa, but all depends on Suarez fitness
