Speculation has been rife that the 28-year-old midfielder will quit in the summer after bagging the goal that wrapped up the championship at Kilmarnock yesterday.

Nakamura's importance to Celtic was highlighted further last night when he was voted SPFA Player of the Year by his fellow professionals at an awards ceremony in Glasgow.

And the Japan international insists there will be plenty more to come from him with the Scottish champions next season.

He said: "I'll definitely be at Celtic Park next season, hopefully to lift my third championship in a row.

"It has been a good season, playing well in the Champions League and we've won the league again. Now our aim is to win the Scottish Cup."

He also urged Celtic to pull out all the stops to ensure manager Gordon Strachan remains at the club next season.

Like Nakamura, Strachan has been linked with a move away from Parkhead this summer, with several English clubs reported to be interested in the former Southampton and Coventry boss.

He has had an uneasy relationship with the Celtic supporters since replacing the revered Martin O'Neill two years ago but Nakamura says the players are well aware of his importance to the club.

"Back when I was in Italy, in three years I had six different managers and I found that really hard," Nakamura said.

"It's important to work under a single manager. If Gordon Strachan stays, that would be great."

Fellow Celtic team-mates Artur Boruc and Lee Naylor were also on the shortlist for the SPFA award, along with Aberdeen skipper Russell Anderson.

Despite coming out on top, Nakamura was keen to play down his own part in Celtic's success this season.

He said: "It's a great honour but I couldn't have done it just by myself - this award is for Celtic as a team.

"I'm glad I won the award and that we won the league but that's finished so we need to look to the future, to the next game."

However, his part in Celtic's triumph and his subsequent Player of the Year award has dominated the headlines back in his native Japan.

He added: "It has been on the news in Japan all over the place for all the people who couldn't come over here.

"It's a good thing for the people of Japan to get to know about Celtic.

"But I never thought about getting these sort of awards when I came here.

"The reason I came here was because I felt that the manager and the chairman really wanted me and they knew my style of play.

"Also, there was the chance to play in the Champions League, which was important to me."
