There was a time when Nottingham Forest and Liverpool were the bitterest of rivals.
Even when Liverpool were sweeping all before them during the 1970s, Brian Clough's Forest remained a thorn in their side, not least when they knocked them out in the first round of the European Cup in 1978.
But by the time of their most recent encounter, some time ago now in April 1999, relations between the two teams had thawed considerably.
The indescribable horror of the Hillsborough Disaster in 1989, when Forest supporters watched on in shock as 97 Liverpool fans were crushed to death at the Leppings Lane End, forged a mutual respect.
