The first reserve team was formed out of the second team of SSV Markranstädt. Its inaugural season was 2009–10 in the Be...zirksliga Leipzig. The team finished in first place and won promotion to the 2010–11 Sachsenliga. As part of the deal with SSV Markranstädt, the team returned to SSV Markranstädt after the 2009–10 season, and played the 2010–11 Sachsenliga as their new first team.
In order to replace the reserve team and to avoid having to begin with its reserve team from the bottom of the German football league system, RB Leipzig partnered with ESV Delitzsch from Delitzsch in northwest Saxony. RB Leipzig adopted the first team of ESV Delitzsch as its new reserve team and purchased its playing right for Berzirksliga Leipzig.[1] The team again finished first place and won promotion to the 2011–12 Sachsenliga, to face the first team of SSV Markranstädt.
With the impending bankruptcy of FC Sachsen Leipzig, which folded in June 2011, RB Leipzig considered purchasing its playing right for the Oberliga for its reserve team, but later withdrew their offer. A condition for the acquisition was that at least 51 percent of the players in the team had to be integrated in the new club, but RB Leipzig instead chose to develop its own reserve team.[2][3]
Tino Vogel was appointed head coach for the 2011–12 season. The team was joined by senior defender Ingo Hertzsch, who had left the professional team. The reserve team came fourth in the Sachsenliga. The league was won by SSV Markranstädt, who recaptured a playing right for the Oberliga.[4] The team finished the 2012–13 Sachsenliga season in third place. The team came first in 2013–14 Sachsenliga, and won promotion to NOFV-Oberliga Süd. Forward Tom Nattermann scored 32 goals during the season, finishing the 2013–14 Sachsenliga as the league's top goal scorer by a wide margin.[5][6]
The 2014–15 season included opponents such as SSV Markranstädt and 1. FC Lokomotive Leipzig,[7] but the reserve team successfully adapted to the Oberliga and came to dominate. The team finished the 2014–15 NOFV-Oberliga Süd in first place, and won promotion to the Regionalliga Nordost. Nattermann scored 26 goals, beaten only by Jan Nezmar from FC Oberlausitz Neugersdorf.[8]
Before the 2015–16 season, almost half of the players from the previous season left the team, including Nattermann, who left for FC Erzgebirge Aue.[8] The new players almost all came from the club's own ranks, including six players from the A-junior team.[9][10] The reserve team finished its first season in the Regionalliga in 11th place.
Incumbent B-junior coach Robert Klauß was appointed head coach for the 2016–17 season, replacing Vogel.[11][12] Vogel continued his career at the club as a scout in central Germany, while his former assistant coach Olaf Holetschek continued as a scout in junior football.[13] The team was reinforced by more players from the A-junior team, as well as 19-year-old talent Dominik Martinović from the Bayern Munich A-junior team.[14] The reserve team was the youngest in the Regionalliga before the 2016–17 season. The average age stood at 19 years and 5 months in June 2016.[15]
