Iaquinta joined Udinese in 2000 and was a member of Italy's World Cup-winning squad in Germany last summer.

A statement on the club's official website, www.juventus.it, read: "Juventus can announce the permanent transfer of Vincenzo Iaquinta for a transfer fee of 11.3 million euros (£7.6m)."

The 27-year-old has signed a five-year contract with the Turin giants, who secured promotion back to Serie A after being demoted to Serie B for their part in the match-fixing scandal.
