In association with Bulb, take on today's quiz and test you knowledge to see if you can name all the teams conquered in Nottingham Forest's record-breaking unbeaten run...
The Reds remained unbeaten for one whole calendar year, from November 1977 to November 1978, a 42-game streak which included lifting the First Division title.
The record was held for 26 years until Arsenal achieved 49 games in 2004, but can you name all 26 different opponents that Brian Clough's Forest faced in the run?
You have 10 minutes to get them all - good luck! Remember to tweet us with how you got on @NFFC, but don't reveal any of the answers!
