Former Italy international striker Christian Vieri has returned to Atalanta for the third time in his career.
The 34-year-old, who played for the Bergamo side in 1995/96 and 2006/07, has agreed a one-year deal after leaving Fiorentina.
Vieri, who won 49 caps for Italy, made 26 appearances for Fiorentina last season, scoring six goals.
His time with Viola ended on a sour note when he missed the decisive penalty in the club's UEFA Cup semi-final penalty shoot-out defeat to Rangers.
However, the return of the former Juventus and Milan striker to Atalanta has reportedly met with a mixed reaction from the club's fans.
Supporters were furious when he left for Fiorentina last season despite a knee injury sidelining him from March 2006 to April 2007.
