DU-RI GETS DADDY OF ALL TRANSFERS.
Du-Ri was hoping to join his father Cha Bum-kun - South Korea's record cap holder with 121 appearances and 55 goals - in the K-league this summer.
But Bum-kun ended his seven-year reign in charge of Suwon Samsung Bluewings to focus on his career as a TV pundit leaving Du-Ri free to join the Hoops on a Bosman.
Du-Ri said: "I chose Celtic because I want to win a title.
"I originally wanted to go to Suwon Samsung because I wanted to win a title with my father but after he quit as coach I changed my plan."
Wing-back Du-Ri stayed on at the World Cup after South Korea's last-16 exit to Uruguay to help his dad as a TV analyst.
And he admits he was heartbroken when Luis Suarez hit a late strike for Uruguay as the South Americans recorded a 2-1 victory in the last 16.
The 29-year-old, who was caught on camera crying as his side crashed out in South Africa, added: "I knew this could be my last World Cup so I thought I would play and have fun.
"Then I felt a deep regret once I realised it was all over. Had we done better in our second-round match I might have still been playing there today."
Du-Ri watched his fellow countryman Ki Sung Yueng impress at the finals with the Celtic midfielder setting up two of his side's six goals.
And while Ki struggled to hold down a regular slot for Celtic last term Du-Ri added: "I spoke with the coach who said Ki will be OK as long as he plays like he did for South Korea at the World Cup."
