And now the Glasgow giants are back in each other's face again. This could get grisly, but let's hope there's a modicum of football played at Hampden.

Old Firm games of recent vintage have thrown up some belters - Rangers beating Celtic 3-2 at Celtic Park in March, Celtic beating Rangers on penalties at Hampden in December after drawing 3-3.

That 0-0 at Ibrox was a blight. The only memorable thing about it was how utterly forgettable it was. Rangers ran around like mad dogs in a meathouse and got a draw having just conceded six to Brugge.

Celtic passed backwards, hesitant and unthreatening having just been knocked out of the Champions League by Kairat Almaty. It was the third time in four matches where they failed to score.

The game produced a combined xG of 0.32. We can't be certain - stats vary - but there's a serious chance that this is the lowest xG ever recorded for a game in Britain since records began.

It certainly felt like one of the most stultifyingly dull encounters in the modern history of the fixture.

This game remains a curiosity. Celtic...
