Napoli land Lucarelli
The 34-year-old has been brought in to replace Argentine German Denis, who recently moved to Udinese.
"I'm happy that this deal is finally concluded, for me it's a great satisfaction to be able to play with the Napoli shirt at the San Paolo stadium in front of excellent fans," said Lucarelli, who has six Italy caps. "It's a dream come true and the fact it's come at 34 is even better."
Lucarelli began his career in the lower divisions but made his name during a four-year spell at Livorno during which time he scored 92 goals in 146 league games, from 2003-2007, earning all his caps during this period.
He also played for Valencia in Spain and Shakhtar Donetsk in Ukraine during his 18-year career.
