Ki Sung-yueng admits winning the Scottish Premier League title with Celtic is the best moment of his career thus far.
The 23-year old South Korea international has been a key part of the Hoops side which clinched the Premiership last week and suggests it was a great experience but insists the team is not done there with Champions League football in the offing.
"Next season is huge and our challenge is to make an impact in the Champions League. We've been watching it on TV and now we want to take part.""Winning the league with Celtic has been the best moment of my career. Our passion and determination was greater than Rangers' this season," he said.
