The Greece international is currently the Parkhead side's top scorer with 14 goals in all competitions.

However, Samaras, along with most of his Parkhead team-mates, has come in for criticism in recent weeks as the Hoops' seven-point lead over Rangers at the top of the Clydesdale Bank Premier League has been reduced to two.

Ahead of the visit of Hibernian, the former Manchester City striker revealed he is always looking to become a better player.

"I'm never happy with myself," he said.

"I always challenge myself to do more. If I play a good game, I always watch the match and look at my mistakes.

"I try to see what I can do to improve.

"I feel good though. I'm happy that I have the support of the club, my manager and my team-mates.

"Of course I want more from myself, but I'm sure that will come."

Samaras, however, insists he does not care who scores the goals for Celtic, providing the club continues its recent success.

He said: "I don't set myself any goal targets.

"The only aims I have are with the club and my team-mates. I don't care who scores. I just want Celtic to win.

"As long as the ball hits the back of the net, who cares who puts it there?

"It doesn't matter if it's me, Scott (McDonald), Jan (Vennegoor of Hesselink), Stephen McManus or Scott Brown.

"All that matters is that the ball hits the back of the net. That's the way I look at it."
