Grosso, now 31, joined Lyon from Inter Milan in the summer of 2007, and was under contract with the French side for a further two seasons.

However, Lyon lost their grip on the Ligue 1 title last season and the World Cup-winning left-back opted to return to his native country.

"I am happy, very happy," he told juventus.it. "I returned home. I really wanted to come to Juve and I managed to make this dream come true. In my career I have always made choices that satisfied me."

Grosso admits the frantic last-minute deal hours before the transfer window closed was stressful.

"Those moments weren't easy but the important thing is that I got what I wanted," he said.

"I am going to Turin with the objective of winning all the competitions. Juve deserves great victories."
