A stand-in for the injured Gianluigi Buffon in South Africa, Marchetti did not cover himself in glory as the then holders crashed out in the group stage.
In truth, he was not at great fault for the goals he conceded but they contributed to his dream move to Sampdoria falling through and thus Cagliari dropping him from the first team squad because of his disloyalty in courting a transfer.

The Romans, relegation candidates last term, visit Bari in Sunday's late game knowing what their rivals have done.
