Cacau?

Can somebody tell me why Joachim Low insists on still including Cacau in his squad? The guy couldn’t even make the starting line-up for his home club in Stuttgart – let alone the National team…and forget the fact that he has dubious credentials to play for the National team to begin with. Low is generally a genius…so i’ll cut him some slack…but I would argue an in-form Helmes or Kiessling might be a better choice.
