Napoli problems upset Cavani
Napoli forward Edinson Cavani says he is enduring the 'worst' spell since his arrival at the Serie A club.
Their chances of challenging for the title have been dealt big blows recently with losses to Inter Milan and Bologna.
But Cavani, 25, is hoping his side can get back on track by claiming victory at Siena on Saturday.
"It's the worst moment during my time in Napoli. We want to win the last 2012 match in order to have a happy Christmas, for us, our fans and for (Gianluca) Grava and (Paolo) Cannavaro," he said.
Walter Mazzarri's men were dealt further blows in their quest for the title after becoming the latest Italian team to be punished in the country's match-fixing scandal.
The club have been hit with a two-point deduction, as well as having Cannavaro and Grava banned for six months for failing to report the incident.
However, Mazzarri is confident he will see a reaction from his side in Saturday's fixture.
"It's a difficult moment, but I'm certain that the team will get back on the right path," Mazzarri said.
"We've identified the reasons behind our dip. We'll see against Siena if the things we have discussed are applied.
"I don't have a magic wand, but I can guarantee that the squad will give everything that it has."
Napoli have had a poor run in December, losing all four games in all competitions, the latest being a defeat at home to Bologna.
Despite the deduction which saw them drop from third to fifth, Mazzarri is proud of what his players have achieved so far this season.
"Despite the points penalty, we have more points now than at the same stage last season," he said.
