The full-back came to Posh from Norwich City in January 2022, but after scoring an FA Cup winning goal on his debut against Bristol Rovers he struggled. Mumba started just seven games for a Posh team destined for relegation from the Championship.
The 24 year-old has been at Plymouth for three-and-a-half years after initially moving to Devon on loan from ‘The Canaries’ and he was a star man in a Pilgrims team that won the League One title in the 2022-23 season.
Klaidi Lolos, who Posh have just loaned to Crawley Town, started his career at Plymouth.
Here are 10 more players who have represented Posh and Plymouth. How many do you remember?
9. JON SHEFFIELD
Posh boss John Still paid Cambridge United £150K for this goalkeeper in 1995 and he initially did well at London Road. He was an ever-present and player of the season in the 1995-96 season. Sheffield became less consistent when Barry Fry replaced Still and he was loaned out to Watford and Oldham before Plymouth paid £100k for him in July 1997. Sheffield spent four years at Home Park and made over 150 appearances for 'The Pilgrims.' He had played 81 times for Posh. Photo: David Lowndes
10. TONY SPEARING
Tough-tackling left-back who played 132 times for Posh between 1992 and 1997, scoring twice. Posh had picked him up on a free transfer from Plymouth in 1993. He had played 40 times for 'The Pilgrims.' Photo: David Lowndes
