However, the January arrival of Barry Robson has left Japanese playmaker Nakamura facing a battle to retain his spot.
With another new signing in countryman Koki Mizuno pushing for a start, Nakamura has chosen to take the pressure to perform as a positive.
"Ever since I came to Celtic, I've not had a trial for my place on the right side of midfield," Nakamura told the Evening Times. "But now Barry has come here and he can definitely play out there and cut inside on his left foot, as I have done in the past.
"It's good to have competition, good the team and for the individuals involved. I must now fight for my place, although Barry can play in more than one position.
"He is a strong player physically and he can play in the centre of midfield or out on the left-hand side as well."
