Rangers striker Alfredo Morelos and Celtic skipper Scott Brown have history.
Recent horrible history.
Just four months ago Morelos saw red after catching Brown with an elbow in the 31st minute of a stormy match Celtic went on to win.
But afterwards Morelos said: "I didn't touch his face and I think that he exaggerated a lot.
"Neither the referee nor his assistant saw what happened. Four Celtic players went over and put pressure on the linesman and then not even five seconds later the linesman told the referee to send me off.
It was Morelos' FIFTH red card of the campaign.
And he claimed on social media: "I promise to do everything in my power to ensure nothing like that happens again and to give the club and the fans my all."
But can he curb his temper in Sunday's first Old Firm fixture of the season?
If you're not convinced thepools.com have an incredible offer.
They're offering odds of 16/1 for Morelos to see red . With Rangers at home they're offering the same price for Scott Brown to suffer the same fate.
And if you think both will get their marching orders they're offering a whopping 250/1 !
Bobby Madden, the official who oversaw that tempestuous clash last season is back in charge again.
Madden showed two red cards, five yellows and Ibrox boss Steven Gerrard later accepted a one-game touchline ban for comments made towards the official.
Tempted?
