After a win against Dundee United thanks to a Robbie Keane goal,all roads lead to Ibrox for Celtic's biggest game of the season so far, writes Sean Graham

Today is the day that the whole of Glasgow and beyond have been looking forward to and maybe dreading,all week.

Much has been written and talked about off the field about other events that could have overshadowed this actual game itself with McGregorgate and Celtic's chat with the SFA about some of the strange decisions that have gone on this season an have had some effect on the Hoops results but let me say this,all of that will fade into the back ground when both teams emerge from the tunnel at Ibrox today.

Some may say that what happened to Allan McGregor in the city centre last week will only make the Rangers goalkeeper even more determined to play at Ibrox today and put in a shift as many think his off the field antics have led to him appearing on both the front and back pages of the newspapers.

Players know that they are being looked upon as role models and you wonder what goes through their minds especially with such a massive week for both Old Firm teams.

I am all for players winding down and relaxing but too many Old Firm players are now being attacked in the city centre or surrounding areas but they now know they must find somewhere a bit more private as McGregor,McGeady,Brown,O'Dea etc will tell you.

This and Celtic's chat with the SFA which has been leeked has not done today's referee any favours.Dougie McDonald will be under even more pressure in today's game from both sides but will these comments come back to haunt them?

Was this the time for Celtic to bring up their concerns about referees? are they right to do such a thing before an already massive Old Firm game?

Only time will tell and the touch paper has been lit even more so now with these comments will rile the Rangers players and supporters even more so but will all of this matter after 12.30 today?

Celtic know that they have to go for it today,no question about that.Rangers have the advantage with the points difference,game in hand,playing at home but we all know that on Old Firm day,anything can happen.

Lets just hope that we get a game to remember and we are not talking about the referee or incidents after the match.

Celtic hope that Robbie Keane is fit in time to face Rangers in what would be his first Old Firm game,this was the game he has been bursting to play in since coming to Celtic on loan and he would be gutted to miss out if his knee injury does not clear up in time.

Rangers manager Walter Smith also has a huge decision to make over Allan McGregor,is he fit enough after not training until Friday? also what will his state of mind be after his assault last week also? They have a more than able deputy in Neil Alexander who will be bursting to get involved in the action.

Whoever plays and whatever the outcome,no doubt there will be talking points to keep us going for the rest of the week and Ravi and all my Rangers pals will text me if the result goes their way,may the best team win and hopefully Murdo McLeod will see a good game too and it will be great to see the wee man out and about again.

Before today's Old Firm match there will be a minute's silence in respect to former Rangers keeper Gerry Neef who died of cancer last week,please take note and respect this!!!
