Christian Vieri has joined Atalanta for the third time in his career.
He has signed a one-year deal after Fiorentina, where he played last season, opted not to offer him a new contract.
Vieri's second spell started after his absence from the 2006 World Cup because of injury and his departure to Fiorentina only a year later left a bitter taste in the mouths of Atalanta supporters, who felt he had betrayed the club which had given him the chance to regain form and fitness.
The majority of fans have therefore been against Vieri's return since it was first mooted earlier this summer, but the club have ignored their protests.
"Atalanta announces the signing of footballer Christian Vieri for the sporting season 2008-2009," read a statement on the club's website.
