It's the type of debate that rages on in work places and pubs the length and breadth of the country.
Celtic and Rangers supporters love nothing more than discussing the merits of the biggest rivalry in the Scottish Premiership .
And former players are no different.
Record Sport's Chris Sutton and Alex Rae know a thing about the fixture and the former stars have come together to select their greatest combined XI...with a twist.
The Celtic and Rangers favourites were only allowed to choose players they played alongside.
Sutton starred alongside a host of Hoops heroes and Rae was part of the Alex McLeish 05/06 side that secured the Double in the most dramatic of circumstances.
The pair had plenty of battles on the pitch and we had our chief football writer Keith Jackson on hand to make sure things didn't spill over.
Every position was up for debate but did Sutton pick himself as one of the two strikers that made the cut?
