Shunsuke Nakamura says he will not decide on his playing future until after Celtic's campaign for the Scottish Premier League title.

The Japanese midfielder has been linked with a move back to his former club, Yokohama Marinos, but insists he will not decide until Celtic's quest for a fourth successive SPL title is complete.

"Maybe I will stay here, maybe I will move to another league or maybe I will go back to Japan," Nakamura told the Daily Record.

"No one knows - I don't know.

"However, I want to concentrate only on Celtic for the moment. I am only interested in winning the title for the fourth season in a row.

"That is more important to me than my future. I don't know if I am going to stay.

"I could have left in January but the situation changed and you never know what can happen at the end of the season.

"I am not worried about it. I am concentrating only on winning the next match."
