Berna's value is seemingly solely based on a function of his nationality and the amount of caps he has for Italy. If he was from, say, South Africa for instance, his value would basically be zero.
But hey, if Italian teams want to pay high amounts for their own dross, go right ahead.
Watch Maldini change his mind Berna doesn't have many talents, but he has something about him that can deceive people - his presence in the Mancini's or Pirlo's lineups cannot be logically explained.
