Marseille have completed the signing of Japanese defender Hiroki Sakai, the Ligue 1 club announced on their website.
The 26-year-old was a free agent after his contract expired at Hannover 96, who were relegated from the Bundesliga last season.
“This is a big club for me. I am delighted,” said Sakai, who made 96 appearances during his four seasons at the German club.
“I can’t wait for the first training session,” he told the club’s website.
Sakai has 27 caps for Japan and was part of the squad that reached the semi-finals of the 2012 London Olympics tournament.
