For every roaring success like George Boyd (£250k from Stevenage in 2007) there are a handful of flops like Tom Nichols (£300k from Exeter, 2016) and Adil Nabi (free from West Brom, 2016).
Here are the players Posh have signed on loan or permanently in January over the last 6 years and where they are now.
Posh didn’t sign a single player in January in the League One promotion season of 2020-21.
