Read our numbers guide to Saturday's game
Chesterfield and Millwall meet for the 38th time this weekend and there has been little to split the two clubs down the years.
The Lions head to the Proact Stadium holding a slight head-to-head advantage with 16 wins from the previous 37 meetings compared to 14 for Chesterfield. The remaining seven matches have ended in draws.
All but one fixture between the two clubs has been in the League, with the only other game being a Cup tie during the 1972/73 campaign which Millwall won 2-0.
In more recent seasons, though, it is Saturday's hosts who have the enjoyed the fixture more, with six wins from the previous 12 encounters, while The Lions have won just three out of those dozen games dating back to the 1996/97 season.
However, one of that trio of victories was in the most recent meeting between Millwall and The Spireites when goals from Aiden O'Brien and Lee Gregory secured a 2-1 win for Neil Harris' side at the Proact back in January.
