The bottom line is that Marotta is out of his depth at a club like Juventus. He might be good for a Sampdoria or Genoa, but he is most definitely not competent enough to be the sports director for a club which harbors serious ambitions and aspirations of competing both locally and internationally.
Marotta is ok for now, but definitely not for the foreseeable future. His knack for relieving other teams of their garbage is sickening and disgusting in equal measure. Borriello, and now apparently Behrami as well? Bochetti if we fail for Caceres? Palombo because we are unwilling to pay up for guys like Guarin or Radja? Not even an attempt to acquire Tevez, when we could have obviously used someone of his immense quality? His deals, particularly in January reek of mediocrity; stop gap solutions! It's always quantity over quality when given the choice. You don't win titles by penny pinching or going for the next best option when you can't get what you want.
He's adopting an Indian Jewish philosophy in his transfers; being cheap, trying to get whatever you want for the price you want, and a lack of willingness to compromise when it comes to quality.
