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.

. JEANDO FUCHS
HIT! Signed from Dundee United, undisclosed fee, 2022. A battling midfielder who has become a firm fans' favourite. 46 appearances, no goals, still at Posh. Photo: Joe Dent
. HAYDEN COULSON
MISS! Signed on loan from Middlesbrough, 2022. Left-back who struggled at Championship level. Picked up a red card at Derby. 8 appearances no goals. Now on loan at Aberdeen. Photo: Joe Dent
. BALI MUMBA
MISS! Signed on loan from Norwich City, 2022. Another full-back who couldn't cope with the Championsip. 13 appearances, 1 goal on debut in the FA Cup. Now doing superbly on loan at League One pacesetters Plymouth. Photo: Joe Dent
. REECE BROWN
HIT & MISS! Signed from Huddersfield on loan in 2020 & in 2022. Decent first spell for the midfielder when his loan continued into the promotion season of 2020-21, but no impact in the second-half of last season. 65 appearances, 2 goals. Now at Forest Green Rovers. Photo: Joe Dent
. STEVEN BENDA
HIT! Signed on loan from Swansea City, 2022. Goalkeeper who performed well in a side doomed to relegation from the Championship. 11 appearances. Now first choice in the Championship with Swansea. Photo: Joe Dent
. CALLUM MORTON
MISS! Signed on loan from West Brom in 2022. Striker who predictably struggled in a poor Championship side. 7 appearances, 0 goals. Now at Fleetwood Town in League One. Photo: Joe Dent
. JACK TAYLOR
HIT! Signed from Barnet for £500K in 2020. The midfielder was a key player in the Posh promotion campaign of 2020-2021. 111 appearabes, 16 goals. Still at Posh. Photo: Joe Dent
. SAMMIE SZMODICS
HIT! Signed on loan from Bristol City, 2020. All-action attacking player who went on to sign for Posh permanently. Scored 15 goals in the League One promotion season of 2020-21. 106 appearances, 27 goals. Sold to Championship side Blackburn Rovers for a reported £2 million fee in August. Photo: Joe Dent
. LEE TOMLIN
MISS! Signed on loan from Cardiff, 2019. A Posh superstar in his first spell at the club. The forward did no better than okay in his loan spell. Loan spell appearances 21, goals 2. Now player-coach at non-league Ilkeston Town. Photo: Joe Dent
. DANIEL LAFFERTY
HIT: Signed on loan from Sheffield United, 2019. A stylish left-back who played well after Darren Ferguson came back to manage Posh. Appearances 21. Goals 0. Now at Derry City. Photo: Joe Dent
. KYLE DEMPSEY
MISS! Signed on loan from Fleetwood, 2019. Steve Evans fancied the midfielder, but Ferguson didn't so barely played. 11 appearances. 0 goals. Now at Bolton in League One. Photo: Joe Dent
21. DOMINIC BALL
MISS! Signed on loan from Rotherham, 2017. A centre-back who struggled to break into the Posh team and reportedly fell out with the manager beforer leaving. Appearances 6, goals 1. Now at League One promotion fancies Ipswich Town. Photo: Peterborough United Football Clu
22. TOM NICHOLS
MISS! Signed from Exeter for a reported £300k in 2016. A striker who scored on his Posh debut, but the rumour that manager Graham Westley never wanted to sign him never went away. He did score a goal in a win over Cobblers though so it wasn't all bad. Appearances 58, goals 14. Now at League Two side Crawley Town. Photo: Joe Dent
23. AARON WILLIAMS
MISS! Signed from Nuneaton for an undisclosed fee, 2016. One of manager Westley's many weird signings. A forward who was way below the required standard. Appearances 10, goals 2. Now at Welsh Premier League club Newtown FC. Photo: Joe Dent
24. ADIL NABI
MISS! Signed on a free transfer from West Brom, 2016. More proof that Westley lost the plot. A midfielder with no obvious pedigree or quality. He struck the bar with a 30 yarder on his debut, but it quickly went downhill after that. Appearances 10, goals 0. Last heard of at Greek club Atromitos FC. Photo: Joe Dent
