Celtic midfielder Ki Sung-Yueng has revealed he has a poor relationship with boss Neil Lennon and is considering moving on.

SNSKi Sung-Yueng has struggled for first-team football at Celtic

Ki, 21, joined Celtic in December last year but, despite impressing for South Korea at the World Cup this summer, he has had limited opportunities with his club.

"I don't need to stay at Celtic as long as I can't get a first-team place," he wrote on Twitter, according to the Daily Record. "The relationship with Neil Lennon isn't that good since last season. He always says I'm not good at defence.

"The manager does not want to see my strengths as he always stresses my weaknesses. It feels like I'll not be in the first team forever."
