A common goal
The rivalry between Glasgow's two major football clubs, Rangers and Celtic, found a ready fan base in Northern Ireland over the decades. The two sets of supporters enjoyed a seething dislike of each other and displayed a level of sectarian bitterness to parallel anything seen in the club's home city.
So it is encouraging to see both clubs working together in Belfast with schoolchildren to address issues like sectarianism and segregation.
They have tapped into the children's love of football to encourage them to meet and play together, lessons which will serve them well in later life. Celtic and Rangers peacemakers? Well, as they say, football's a funny old game.
