Juventus has never had a more costly failure than a promise that never becomes a reality. It's a phrase that seems written just for telling the story of Dusan Vlahovic's journey at Juventus. The Serbian attacker's adventure in bianconero has come to an end, leaving behind a long trail of unfulfilled expectations, missed opportunities, and numbers that make you think. When in January 2022 Juventus decided to sign him from Fiorentina, the operation was presented as the move that would launch a new era. And the goals against Verona and Villarreal impressed everyone. Four years later, however, the impression remains of one of the most disappointing and expensive operations in the club's recent history. Because Vlahovic was not just an important investment: he was the second most expensive player in Juventus' history, after Cristiano Ronaldo. And his performance has never been worth the final bill. Juventus pays 70 million euros to Fiorentina for Vlahovic's transfer, while his contract makes him the second most expensive player in the club's history.
