World Cup winner Vincenzo Iaquinta moved to Serie A struggler Cesena on loan from Juventus, who signed Atalanta midfielder Simone Padoin on the last day of the winter transfer market on Tuesday.

Iaquinta joined Juventus from Udinese in an ?11 million ($14.5 million) deal in 2007 but has struggled with injuries over the past two years and has not played since last March.

''I'm happy, now I have to prove myself again,'' the 32-year-old Iaquinta said. ''I can't wait to start, I want to relaunch myself. I've had a lot of injuries in my career, I've been unlucky.

''I want to thank all at Juventus, especially the fans, as they always treated me like a great footballer. I have no regrets.''

Iaquinta won the World Cup with Italy in 2006.

Midfielder Michele Pazienza also left Juventus. The 29-year-old Pazienza returned on loan to Udinese, the club he last played for seven years ago.

Padoin completed his move to Turin, signing a five-year deal with the Serie A leaders. Juventus has paid almost ?5 million ($6.6 million) for the 27-year-old midfielder.

Meanwhile, AC Milan completed the signing of teenage striker Philipp Prosenik from Chelsea and Valeri Bojinov has returned to Lecce on loan from Sporting.

Milan, along with Juventus and Bayern Munich, tried to sign Prosenik in 2009, but the young Austrian opted to join Chelsea's academy.

Prosenik started well in England but has had lengthy spells on the sidelines because of serious injuries. The 18-year-old striker is the son of former Austria midfielder Christian Prosenik.

Bojinov started his career at Lecce - making his Serie A debut at 15 - before moving to Fiorentina in 2005.

The 25-year-old Bulgarian had been suspended by the Portuguese club following his actions in a cup game against lower-league Moreirense.

With the game at 1-1 in injury time, Sporting was awarded a penalty and Bojinov - who had not scored a spot kick in nearly six years - pushed aside usual penalty-taker Matias Fernandez and placed the ball on the spot. Sporting fans booed and Bojinov's effort was saved.

The transfer window closes at 7 p.m. local time (1800 GMT).
