Celtic and Rangers will face each other for the first time in almost three years today, with police warning supporters they will crackdown on any signs of trouble.
The League Cup semi-final match at Hampden Park in Glasgow is a sell-out and will have an international TV audience with 54 countries screening the game.
Tensions are set to be high in what is the first game between the clubs since Rangers' liquidation in 2012 and both clubs have been visited by Police Scotland to remind players and management of their responsibilities in a bid to minimise any possibility of trouble.
Officers have said they will be monitoring social media as well as having an increased presence on streets in and around Glasgow.
Police will be deployed at the stadium, in Glasgow city centre and at major transport hubs before, during and after the match.
Chief Superintendent Andy Bates, the match commander, said: "I am sure that most supporters will enjoy the sporting occasion, however a minority may choose to cause disorder and my message to them is clear: anyone involved in disorder will be arrested."
Celtic manager Ronny Deila praised the "world-class" ability of Leigh Griffiths as he revealed that another striker, John Guidetti, had delayed talks over his long-term future.
Griffiths has started the last two games - his first starts in the Scottish Premiership since August - and rewarded Deila with a goal in Wednesday's 4-0 victory over Motherwell, which sent the Hoops top of the league.
There is big competition up front and it's also about the opponents we meet but Leigh has made improvement in a lot of things. He looks sharper now and needs even more confidence.
I believe in him. I think he's a very exciting player and his left foot is world-class, I've not seen any player have a better left foot in my life.

Celtic winger Aleksandar Tonev has lost his appeal against a seven-match ban for using racist language.
A Scottish Football Association appeal tribunal threw out the appeal after the on-loan Aston Villa winger was earlier banned over an incident involving Aberdeen full-back Shay Logan.
The SFA has published the report of both panels who examined the case.
Celtic manager Ronny Deila had earlier indicated the club would challenge the decision further if it was upheld.
Celtic's Aleksandar Tonev has been suspended for seven matches for using "offensive, insulting and abusive language of a racist nature".Read the full story ›
Celtic made an £11.2 million pre-tax profit last season despite a significant drop in revenue.
The club's annual accounts showed group revenue decreased by 14.6 per cent to £64.7 million, with some of the fall being attributed to a £100 reward to season ticket holders.
Operating expenses also fell, by 4.5 per cent to just under £60 million, to leave Celtic with almost £4 million in the bank on June 30.
Celtic have been reinstated in the Champions League despite a humiliating 6-1 defeat on aggregate to Legia Warsaw - who played an ineligible player.
The Polish side brought on Bartosza Bereszynski, who should have been suspended, as a substitute with four remaining minutes in their 2-0 victory at Murrayfield.
Uefa ruled that Legia Warsaw must forfeit their second leg match and awarded Celtic a 3-0 victory - meaning the Scottish champions progress on away goals.
If a side fields a suspended player they must forfeit the match, according to Uefa rules.
Legia Warsaw have the right to appeal the decision.
Five Celtic fans have been jailed in Amsterdam for their involvement in violence before the Champions League match against Ajax in November, according to reports.
Two of the men were sentenced to two months, one to one month and two to six weeks while one was acquitted.
Celtic Football Club said there was "no excuse for any form of violent conduct," but added: "There is no question that Celtic supporters have been subjected to a high degree of provocation."
The Scots were accused of violence in a public space and reportedly denied the charges.
Dutch police said 28 Scots were among 44 people arrested in the wake of the clashes which left eight police officers injured.
The manager of a Kazakh football club has refused to rule out sacrificing a sheep ahead of a game against Celtic in Glasgow.
Shakhter Karagandy boss Viktor Kumykov said the ritual may go ahead before the team's Champions League play-off second leg tie at Celtic Park on Wednesday.
At a pre-match press conference Mr Kumykov said that it would not be too difficult to find a suitable animal in Scotland.
When asked where he planned to get the sheep, he replied: "As far as we know in Scotland the agriculture is very developed so it shouldn't be an issue to find a sheep."
Celtic striker Anthony Stokes has been released from police custody after being arrested for an alleged assault on an Elvis impersonator.
