Cha Du-Ri leaves Celtic to join Fortuna Dusseldorf
Celtic right back Cha Du-Ri has left the club to join German outfit Fortuna Dusseldorf.
The South Korea defender, 31, struggled to make an impact at Celtic following his move from Freiburg in July 2010.
He scored twice in 44 appearances for the club but had fallen down the pecking order under Neil Lennon.
"Everyone at the club would like to wish Cha every success in his future career," Celtic said.
Du-Ri has previously played for Bayer Leverkusen, Arminia Bielefeld, Eintracht Frankfurt and Mainz.
He was vying for the right back berth with Adam Matthews, Mark Wilson and Mikael Lustig.
"The German-born South Korean internationalist returns to football in the land of his birth," Celtic added on their official website.
