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.
17. ANTHONY GRANT
MISS! Signed from Port Vale for an undisclosed fee. To be fair the midfielder was borderline hit and miss. He was effective, but limited. Appearances 59, goals 0. Now unattached having left Scunthorpe at the end of last season. Photo: Joe Dent
18. JUNIOR MORIAS
MISS! Signed from St Albans for an undisclosed fee, 2017. A forward with a powerful shot who couldn't maintain a starting place. Appearances 51 (28 as a sub), goals 11. Now at Dagenham & Redbridge in the National League. Photo: Joe Dent
19. MARTIN SAMUELSEN
MISS! Signed on loan from West Ham, 2017. The midfielder had enjoyed a decent first loan spell at Posh two years earlier (he wasn't a January signing then), but he was poor when he came back for a repeat loan. Total Posh appearances 32, goals 2. Now at Norwegian club FK Haugesund. Photo: Joe Dent
20. CRAIG MACKAIL-SMITH
MISS! Signed on loan from Luton, 2017. Loved Posh so much this club legend had three spells at London Road. Sadly his last spell was a poor one although he did claim his 100th club goal in a game against Oxford. Appearances (last loan spell) 18, goals 5. Now at Southern League side Bedford Town.
