The Rams are confident they will get 30,000 fans through the turnstiles. A win for the home side would take them above Posh on goal difference, although Darren Ferguson’s men would have a game in hand.
Posh fans have played their part already. At 11am today (February 17) they only had a handful of tickets from their 1,800 allocation still unsold.
Posh have only played in front of four crowds in excess of 30,000 in the club’s 62-year Football League history. One came at Pride Park on the opening day of the 2009-10 Championship season when Derby pipped newly-promoted Posh 2-1.
The other plus-30,000 crowds for a Posh game arrived v Newcastle (43,067, 2009), v Crystal Palace (36,478, 1960) and v Middlesbrough (32,503, 1967).
The Palace attendance was for a Division Four match.
Posh have sold just under 500 tickets for the Championship game at Fulham on Wednesday, February 23
