Call it whatever you want, but on Sunday afternoon much of the country will come to a standstill for a football fixture. A fixture, that regardless of how you choose to define it, is the only blockbuster event Scottish football has to offer. The derby world renowned as the ‘old firm’ returns to Hampden for the second consecutive year – after a three-year absence due to Rangers’ relegation to Scottish football’s bottom tier in 2012. With more social and footballing history worth discussing and a depth of passion often regarded as unprecedented by those who have played, managed and attended – the fervour surrounding these games cannot be replicated.
