Udinese face a crisis in midfield ahead of their trip to face Serie A leader Juventus.

With Ghanaian Kwadwo Asamoah and Nigerian Emmanuel Agyemang-Badu competing at the African Cup of Nations, coach Francesco Guidolin (pictured) could give 19-year-old Cristian Battocchio a rare start.

Juventus have completed the signing of Sevilla defender Martin Caceres.

The Uruguay defender, who played for the Turin club in the 2009-2010 season, would become Juve's second signing in the January transfer window following the acquisition of striker Marco Borriello from Roma.

Claudio Marchisio, Simone Pepe and Mirko Vucinic will undergo late fitness tests.

Fiorentina's new striker Amauri has denied delaying his move from Juventus in the hope of receiving a better offer from AC Milan.

The Brazilian-born player, who has not figured at all this season for Antonio Conte's Juventus, finally signed a deal with struggling Fiorentina on Tuesday after a long, drawn-out process.

"I'm happy to be in Florence," Amauri said at his official presentation. "I was offered a two-and-a-half-year contract but I signed for six months as I wanted to first prove myself as a Fiorentina player. What's been said about waiting for Milan is just not true."

Amauri could team up with Stevan Jovetic in attack for Sunday's Tuscan derby against Siena (1130) should the Montenegrin recover from the muscle strain that led to him missing last weekend's goalless draw at Cagliari.

Twelfth-placed Parma have signed Stefano Okaka on loan from Roma with the option of buying the Italian striker outright at the end of the season.

The 22-year old, who has already been loaned out to Modena, Brescia, Bari and Fulham, goes into new coach Roberto Donadoni's squad for Saturday's trip to Catania.

Sixth-placed Roma have converted striker Fabio Borini's loan into a co-ownership deal with Parma. With three goals this season, the 20-year-old looks set to keep his place in Luis Enrique's starting line-up for Sunday's visit of Bologna.
