Vieri quits Atalanta following fan jeers

The 35-year-old, who has hardly featured this term because of injury and lack of form, reacted furiously after being jeered by fans at the training session. His contract was up at the end of the season and media has speculated he may now retire.

"Atalanta announce that Christian Vieri has expressed a wish to terminate his contract with the club early. Atalanta, taking note of the wish of the player, have agreed," a statement read.

The much-travelled forward, who had his most successful spells at Atletico Madrid and Inter Milan, had struggled to regain the trust of Atalanta fans after he quit the Bergamo club two years ago to join Fiorentina, only to return in June.
