Full-back Mumba (20) scored on his Posh debut in an FA Cup tie against Bristol Rovers in January, but only started eight games for the club before returning to Carrow Road.
He’s one of many old boys lying in wait for Posh in the 2022-23 League One season, but should any of them be feared?
Mumba is doubtless a much better player than he showed at the Weston Homes Stadium where he was rarely deployed in his best position as a dashing right-back.
He gets a fear factor rating of 6/10. Other Posh old boys in League One are...

. NATHANIEL MENDEZ-LAING - Derby County.
Posh apps/goals: 100/11. An astonishing 63 of those Posh appearances were as a substitute after the winger moved to London Road from Wolves in 2010. Scored in that infamous last day defeat at Crystal Palace and also scored the 100th Posh League goal of the 2010-11 season. Since leaving Posh he played in the lower divisions with Rochdale and in the Premier League with Cardiff City. He was at Sheffield Wednesday last season. Troubles off the field have diminished his talent, but the 30 year-old has now secured a move to a big club which could rejuvenate him. Fear factor 7/10. Photo: Joe Dent
. JAMES CHESTER - Derby County
Posh apps/goals: 5/0. The centre-back played just a handful of times when on loan from Manchester United in the League One promotion season of 2008-09. Now 33, and after spells at Stoke City, Hull City, Aston Villa and West Brom, he's another to have signed on to try and help Derby towards former glories. A Welsh international who should be strong at League One level. Fear factor 8/10. Photo: David Lowndes
. SCOTT LOACH - Derby County
Posh apps/goals: 5/0. A 34 year-old goalkeeper who played 5 times for Posh on loan in the 2014-15 season. He played for National League Chesterfield last season so he can only have been signed as back-up at a Derby team who will be striving for promotion from League One this season. Fear factor 1/10.

. REECE BROWN - Forest Green Rovers
Posh apps/goals: 65/2. The neat-passing midfielder enjoyed loan spells in three successive seasons at Posh and performed well when promotion from League One was achieved in the 2020-21 season. Now returned to his first senior club after failing to make a single Football League appearance for Huddersfield Town in three years. He's still only 26 and could benefit from a return home. Fear factor 6/10. Photo: Joe Dent
. DOMINIC BALL - Ipswich Town
Posh apps/goals: 6/1. Classy centre-back who played fleetingly on loan at Posh from Rotherham in 2017, but became frustrated at a lack of first-team opportunities. Since forged a decent career at Aberdeen and QPR before joining Ipswich in the summer at the age of 26. He played for QPR in a defeat at London Road last season, but likely to excel at League One level. Fear factor 7/10. Photo: Joe Dent/theposh.com.
. CALLUM MORTON - Fleetwood Town
Posh apps/goals: 6/0. Striker who seemed like a panic signing by Posh last January and who made no impact before returning to parent club West Brom. Now signed permanently at Fleetwood for whom he struggled in front of goal when on loan in the first-half of last season. Fear factor 5/10. Photo: Joe Dent
. ETHAN HAMILTON - Accrington Stanley
Posh apps/goals: 45/1. Energetic midfielder who played a part (mostly as a sub) in the Posh promotion of 2020-21 before moving to Accrington that summer. He enjoyed a strong first season at Stanley scoring eight goals and the former Manchester United man once scored a beauty for Rochdale at London Road. Fear factor 6/10. Photo: Joe Dent
. RICARDO SANTOS - Bolton Wanderers
Posh apps/goals: 75/1. A giant centre-back plucked from the depths of non-league football by Posh in 2013. He was steady enough - and his one Posh goal was a memorable late winner at Darren Ferguson's Doncaster - but he left under a cloud and with some regrettable social media comments before turning into a star turn at Bolton. He's their captain and a fans' favourite and few who saw him at Posh would have seen that coming. Fear factor 7/10. Photo: Joe Dent
. DANNY ANDREW - Fleetwood Town
Posh apps/goals: 2/0. A Posh youth team player who didn't make it at first-team level, but he's turned into a strong lower division left-back with a reputation for deadly accuracy at set-pieces. Andrew (pictured, right) played well at Doncaster for current Posh boss Grant McCann and scored for Fleetwood direct from a free-kick in the first game of the 2019-20 season. Fear factor 6/10.
