This one is more serious than Dzeko. Here we have meetings, contacts, statements from officials.
With Dzeko it was never like this. With him it was newspapers linking Juve to him, but we never heard Juve's or Wolfsburg's directors saying anything concrete. In the winter, when Dzeko left Wolfsburg, Juve couldn't sign him because there is only 1 non-EU spot per season in Italy, and Juve filled it with Krasic.
