Yep, nobody has a clue about what sort of player Ballack is except for Burke and a couple others.
Emerson would be the holding midfielder for Juventus, Vieira and Ballack would roam forward more and support the attack. If we play with four in midfield Ballack would take a role next to Emerson or Vieira, whichever one Capello prefers. If Ballack is able to adapt, he could play on the left side of midfield as well.
So what does this mean? Ballack can play almost anywhere in midfield. Is that so hard to understand people?
