IT'S an obvious observation for any regular visitor to Celtic Park: Scott McDonald is greedy. Just like most strikers.

After all, you don't lay claim to 31 goals in one season by spraying benevolent passes across the box.

The little Aussie will always try to hog the chance for glory, but this season his appetite is even sharper.

With McDonald sitting on six goals so far this season, overcoming his total for last term might be a tall order, but his aspirations centre around the bigger picture.

"This club as a whole is about winning," he said. "I want to make it four-in-a-row by getting the title but I'm greedy; I'd like the League Cup and the Scottish Cup as well.

"I think it would be a really special achievement to win a Treble. It is something that is rarely done and it would be a momentous achievement.

"It isn't something you get the chance to do often, but we approach every game we play trying to win it and we have managed to get ourselves into the semi-final of the League Cup. That'll be a hard one for us, but I'd love to win everything we could this season."

Having set the pace for himself last season, McDonald initially struggled to cope with what was expected of him at the start of this term.

The goals took a while to come and, having been laid low with a virus this week - that kept him out of last weekend's game against Accies and Australia's World Cup qualifier - he is keen to make up for lost time.

However, the idea of ensuring he finishes this season having banged in close to last season's tally is something that McDonald is trying not to think about for fear of buckling under expectation.

"I don't think I could put that kind of pressure on myself," he said. "I just want to take things week by week and let it add up come the end of the term.

"I'll have a look back then and see how I have done, but I would have to say that when it gets to the end of the campaign, I want to be reflecting on a season in which we have won the league and hopefully some other silverware. That for me is more important than bettering the 31 goals as it is all about making Celtic as successful a team as we can be."

He added: "Getting goals is nice and you always feel confident when you are hitting the back of the net.

"But lifting the league title is a special feeling for everybody connected with the club and we know every season that is the big prize we have to go for.

"At the start of the season when goals weren't coming, I don't think it was ever about confidence, more about fitness. As soon as that started to come back then so did the goals.

"When you're tired you make mistakes and you don't do things in the right way and at the start of the season that's what was happening. But once I got my fitness up, my mind was right and I feel that things have been falling into place."

While McDonald's attention is taken up with how best to put the ball in the net, he has revealed his admiration for someone whose job is doing the exact opposite.

Gary Caldwell has shown impressive form this season.

And, for someone who was in danger of becoming something of a whipping boy at the club, his renaissance in the eyes of the Celtic support has been considerable.

Hitman McDonald is full of admiration for the way that the big centre-half has coped with the stick he took regularly last season.

"He has belief in himself and for all the slagging he got at times last season, he just put his head down and got on with it. In the dressing room with us he would just have a good joke and a laugh about it at his own expense," he said.

"With some people you would say that is just a deflector but with him he genuinely didn't let it get to him.

"He would try the same passes again even if they didn't come off for him and his attitude is fantastic."

"Gary is a great guy in the dressing room. Alongside big Stephen McManus, he is a natural leader and they are playing tremendously well together just now."

The Aussie continued: "Gary has been outstanding this season. He is a rock at the back and the gaffer has often said that he takes anything on his shoulders.

"He has played at right back, as a holding midfielder, as a central defender - he will do anything for the team.

"He doesn't get the credit he deserves for being able to see a pass and play the ball out of defence.

"He is also another one who is not that old and I think he will get even better in the years to come."

Meanwhile, Cillian Sheridan has risen to the fore in the last month given the crippling injuries Celtic have had.

The teenager was thrown in at the deep end and has been tutored by McDonald in big games these past few weeks.

"Cillian has done really well because he has had a difficult time with injury over the last few years," said McDonald.

"He is lucky because he is a naturally fit lad and with his build he is never going to be one to carry any weight.

"He has done tremendously well and I think the manager might want to be a wee bit careful with him just because of the injuries he has had.

"But he has really given the manager something to think about it and I'm sure he will feel pretty satisfied with his contribution."
