It’s a clash between second and third and so one of the most important matches in Posh history.
The perfect opportunity then to see how Posh fared in some of the other biggest matches in the club’s Football League history.
We’ve excluded play-off games to concentrate on the regular season ‘biggies.’

April, 2008, League Two. Hereford 0, Posh 1. A Dean Keates goal secured victory and Darren Ferguson's first promotion as Posh boss. Hereford were one of Posh's biggest rivals that season and also earned promotion from a third place finish. Posh finished second behind champions MK Dons. Keates is pictured celebrating his goal at Edgar Street.

May, 2009, League One. Colchester 0, Posh 1. Posh completed back-to-back promotions on a nerve-shredding afternoon at Colchester thanks to Charlie Lee’s goal. It was the penultimate game of the season and Posh had to wait several minutes before it was confirmed MK Dons had lost at home to Walsall so Darren Ferguson's men has sealed second spot behind champions Leicester City. Ferguson is pictured celebrating with striker Aaron Mclean.

March, 2009, League One. Posh 2, Leicester City 0. Two months earlier that season at London Road there was a huge clash. Leicester were top of League One, Posh were second. Goals from Charlie Lee and Chris Whelpdale secured the points for Posh who confirmed they were title challengers as well as promotion candidates. Posh players are pictured celebrating Lee's goal.

May, 1990, Division Four. Posh 1, Southend United 2. It was the final game of the season at London Road and Mark Lawrenson's Posh had to win to finish in the play-off places, while Southend had to win to clinch automatic promotion. Sadly the visitors eased into a 2-0 half-time lead and a Mick Halsall (pictured) goal early in the second-half wasn't enough. POsh finished 9th. Photo: Midlands
