Celtic boss Ange Postecoglou was greeted by an unlikely friend at Ibrox on Sunday in the shape of Rangers icon Ally McCoist.
The Hoops manager and his squad made the short trip across Glasgow for the mouthwatering showdown in their quest to win this season's Premiership title.
And whilst he was probably preparing himself for the usual hostile welcome, Postecoglou might've been shocked to find himself face-to-face with McCoist, who was typically smiling from ear-to-ear.
As Rangers top-scorer, as well as having managed to Ibrox club, McCoist knows all about the pressures of a derby showdown like this one, particularly when one side seemingly has the chance to land a knockout blow on their bitter rivals.
A Celtic win today would take them six-points clear at the top of the Premiership table, with just six games to play - and the final fixture between the top teams this season set to take place at Parkhead.
They were all smiles before noon but it remains to be seen which of the due will still be on top form at the full-time whistle.
