Michael Ballack and Lukas Podolski almost came to blows in the second half of Germany’s 2-0 victory against Wales.Podolski slapped Ballack because he apparently did not like what his captain was telling him.The mystery of what Ballack actually said to rile Podolski is going to rank alongside other great soccer mysteries of our time like what Materazzi actually said to Zidane or why Cristiano Ronaldo keeps falling down in the penalty area .Either Ballack or Podolski will write a book eventually and then we will know.At least it didn’t end in a head butt.
