Celtic last night held on for a 2-1 win over Inverness at Parkhead as the Gers were strolling to a 4-0 triumph at Hearts.

The Ibrox side's 10th successive Clydesdale Bank Premier League win kept them four points ahead of Celtic in the title race.

But, with three Old Firm games still to be played, Gordon Strachan's team have the chance to win the title in their own hands.

And Nakamura, who set up Scott McDonald's 25th goal of the season with a free-kick last night, believes they must maintain their focus.

"We just need to play our football and we just need to concentrate on what we should be doing," he said.

"We need to look to win the games rather than waiting for other teams to get beat. That's what we have to concentrate on."

Nakamura was promoting the PFA Scotland Player of the Year Awards, after winning the top prize last season.

The Japan international is unlikely to repeat his success after missing 10 weeks of the season with a knee injury, but he believes there are plenty of contenders to keep the trophy at Parkhead.

"I was really pleased that it was everyone from other teams rather than your team-mates who voted," he said.

"If Aiden (McGeady) plays the way he is just now he has got a great chance.

"I think Artur Boruc and Stephen McManus are also playing really well."

Players are not allowed to vote for team-mates so Nakamura was set to plump for a Rangers player, until Alan Hutton signed for Tottenham in January.

"I was thinking Alan Hutton but he has gone so I will have to think about that again," the 29-year-old said.

PFA Scotland chief executive Fraser Wishart believes there are a host of players in the running, including McGeady, McDonald and Rangers defender Carlos Cuellar.

But he also thinks players from outside the Old Firm are in with a chance, such as Dundee United striker Noel Hunt.

Wishart said: "There have been outstanding performances. It was great to see Rangers, Celtic and Aberdeen progress in Europe.

"Motherwell and Dundee United have had good seasons, United are in a cup final.

"Alan Hutton would have been one of the candidates had he not gone to Tottenham.

"McGeady has been outstanding. He looks faster and stronger and he can play for 90 minutes.

"Him and Scott McDonald have had a huge influence on Celtic's season.

"I hope to see players outwith the Old Firm in the shortlist, Noel Hunt has scored a barrowload of goals.

"Ross McCormack has been fantastic for Motherwell, that would be just reward for the outstanding season they have had."

Nakamura could still win the award next season though after repeating his intention to stay at Celtic until no longer wanted.

The midfielder's contract expires in the summer but Celtic chief executive Peter Lawwell has the option of extending it for another 12 months.

"I'll be here until Peter and Strachan say I don't want you any more," he said.

His former club, Yokohama Marinos, have expressed a desire to re-sign Nakamura and the Japan international again confirmed his desire to return there before he retires.

"I am thinking that I just don't want to finish my career abroad," he said.

"That's the team I grew up at so that would be great to contribute to that team."
