The Celtic players will wake up tomorrow morning knowing that they are within touching distance of making their own bit of history.

Amid the excitement of going through an entire campaign unbeaten – and more on that later – I think that you can’t look any further than Aberdeen and the chance to go out and cap this season with a Treble.

It is real chance for this team to go and write their names into the fabric of the club in a campaign in which they have paid the ultimate tribute to the Lisbon Lions by the manner in which they have went about their football.

As someone who missed out on the chance to win a Treble, my only advice would be to keep the focus, keep the momentum going and concentrate on what lies ahead for one more game before getting the party hats on.

In my inaugural season in the senior team in 1969/70 we almost did a quadruple but were foiled in the Scottish Cup against Aberdeen and the European Cup final against Feyenoord.

Eddie Turnbull was the Aberdeen manager who presided over that win at Hampden but we were officiated by the worst referee in the country, Willie Davidson. He was regarded as the best in the eyes of the top brass but – and there is not a hint of sour grapes here but rather a simple fact – he did not like Celtic.

It really was as black and white as that.

That aside, I know what it is like to be within touching distance of a clean sweep and then stumble at the finish.

Aberdeen will give Celtic a good game and although I would suggest that Celtic have enough to prevail, you always have to appreciate that in a one off game anything can happen.

You need the right approach going into the game and I have to say that I think Celtic, under Brendan Rodgers, will have that.

To go back to the Invincibles achievement, I just don’t think you can overplay it. It is an absolutely astonishing thing to do at any level of football, to go through an entire campaign without losing a game.

I think you have to go back to when Adam and Eve were still kicking about to find out the last time it happened – and even then, they only played 18 league games.

What has been particularly impressive is that they have done it by playing football the way that Celtic teams have always sought to play; it has been focussed on attack, it has been fast, it has been exciting, there have been more goals scored this season than in any other campaign in the modern Premier League.

But before anyone gets too carried away about where Celtic go from here and how you set the bar next season, I think you just don’t go any further than Saturday and what lies in wait at Hampden.

There are only three Trebles so far in Celtic’s history and this is a day to go out and do something momentous.

I do think that the plans are already in place for what comes next – and we all know that revolves around the Champions League qualifiers.

I appreciate I am at risk of repeating myself, but I do think that these games essentially define the season. Getting into the Champions League group stages is what it is all about and I am pretty assured that there will already be one or two players pin-pointed to bring to the club to help facilitate that journey.

This season has been a revelation – but it isn’t over yet.

There is history to be made and it is exciting for the club to be where they are from where they were a year ago.

Not to appear as though I have a crystal ball or anything, but I actually said two things that have been proven correct over these past few months; one, that this was a Celtic side that needed leadership and direction but not major surgery this time last season and two, back in October, I wondered just who would beat Celtic domestically.

You have to take your hat off to Brendan Rodgers – and to the players. He has led them to water but, boy, have they taken a drink. The sheer energy and ruthlessness of them as well as the constant desire to win has been exceptional.

It has been an incredible season and you have to fancy that they will go now and finish it off by crossing the line against Aberdeen.

When it comes to Rodgers I think there is always a sense that you know he just won’t allow his players to take their eye off the ball which leads to a trust on all sides.

He will want to get his hands on the Scottish Cup to complete the Treble at the first ear of asking. He will want it for himself and for his players but also for the supporters.

He has had the full backing of everyone since he arrived and I am sure it will give him a lot of satisfaction to go out and deliver the final piece of the jigsaw.
