Mutu was sacked by English Premiership club Chelsea last October for testing positive for cocaine and agreed a five-year contract with Juve last month.

However, the Romania international will not be able to play for his new employers until May 18 when his worldwide ban ends.

"I am happy because my life has taken on a new meaning after a terrible period," said the 25-year-old striker when unveiled at a press conference in Turin on Tuesday.

"I believe I have matured and will benefit from this experience. Juventus are one of the strongest teams in the world and I can't wait to be involved."

Juventus coach Fabio Capello, whose team have an eight-point lead at the top of Serie A, said Mutu was an excellent addition to the squad.

"He is one of those players who will give us an extra bit of quality. We have been looking for a player like him and the deal is an excellent one as we got him for free."

Mutu arrived at Chelsea from Parma for 15.8 million pounds (29.7 million dollars) in August 2003 and made an instant impact, scoring in his first three games for the Londoners.

But his fortunes quickly deteriorated and a dramatic dip in form that saw him go 19 games without scoring was followed by a sex scandal involving a Romanian porn star.
