Those nominated are here along with updates on where they are now.
The PT put forward Ken Charlery as one surprisingly good arrival.
He was a gangly, clumsy and pretty hopeless right winger when he pitched up at London Road as one of six transfer deadline signings made by legendary manager Chris Turner in March, 1991.
Posh paid Maidstone a paltry £5k for his services, but once moved to a centre-forward role he quickly turned into a club legend scoring 26 goals in his first full season including two in a Third Division play-off final at Wembley which secured his club a place in the second tier of English football for the first time.
The PT pick for most disappointing signing was Mick Lambert, a top-class winger in the top-flight with Ipswich Town who bombed at London Road after arriving in 1979. He only played 18 times in two years, scoring twice.

13. IVAN TONEY
Posh helped turn him into a superstar after numerous loan spells around the Football League. Now a Premier League player and an England international. 'I thought he was brought in to challenge Matt Godden and Jason Cummings for a starting spot. Turns out he was pretty good.' @theposhfan Photo: Joe Dent
14. JOEL RANDALL
A million pound signing from Exeter City who has yet to fire. Still at Posh. 'Still waiting on Joel, but I am not holding my breath.' @nige_cornwall58 Photo: Joe Dent
15. ERNIE MOSS
A prolific lower division goalscorer, except when he was at Posh. Nominated by @Nimrod57. Sadly passed away in 2021 after suffering with dementia believed to be linked to heading a football. Photo: PT
16. The Holy Trinity
Aaron Mclean, Craig Mackail-Smith and George Boyd were all plucked from non-league football by Posh and turned into Premier League players. All now retired with Mclean forging a fine career as a pundit. 'Did anyone think they'd turn out like they did?' @DE180YPOSH Photo: Joe Dent
