[3] In 1979, with Persib relegated to the Perserikatan First Division, Djadjang accepted an approach to move to the newly formed Galatama, joining Sari Bumi Raya who were based in Bandung.

[2][3] After Mercu Buana disbanded, Djadjang decided to return to Bandung and was immediately called into Nandar Iskandar's Persib squad for the 1986 Perserikatan season.

[2] Following Iurie's departure, Djadjang had a brief stint as Persib joint caretaker head coach alongside his former teammate and captain Robby Darwis in the 2007–08 season.

At the end of his caretaker stint, he accepted a role as assistant coach at Pelita Jaya under Fandi Ahmad.

In 2011, Djadjang was appointed as Pelita Jaya's caretaker head coach after Fandi Ahmad left the club.

He managed to save the club from relegation before returning to his previous role under newly appointed head coach Rahmad Darmawan.

[3][4] On 13 August 2012, Persib appointed Djadjang as the team's new head coach in a closed meeting at Holiday Inn Bandung.

[8] For this season, Persib filled their foreign player quota with Vladimir Vujović, Djibril Coulibaly, and Makan Konaté.

They would face off against Western Group winners Arema Cronus in the semifinal and beat them 3–1 after extra time with late goals from Vladimir Vujović, Atep Rizal, and Makan Konaté sending Persib to the final.

Djadjang would succeed in bringing Persib the title with a 5–3 penalty shootout win over Persipura Jayapura after the match ended 2–2 in 120 minutes.

[2] For several months in 2016, Djadjang went into coach training in Italy as part of a partnership between Persib Bandung and Italian side Inter Milan.

In preparation for the 2017 Liga 1 campaign, Persib made some big-name signings that signalled their established status as two former Premier League players joined the club.

[15][16] Before their arrival, Persib had made other signings with the likes of Ciro Alpes, Imam Murahidal D, and Semarang attacking midfielder Muhammad Agung Divyatma coming into the squad.

[17] The team's poor form was summed up by Carlton Cole being released by the club on 13 July 2017 after starting only two of his five appearances, scoring none.

[18] Finally, on 15 July 2017, Djadjang officially resigned as Persib head coach after he was disappointed that he could not boost the team's performance.

[27] At the start of the following year, the club reached the finals of the Indonesia President's Cup pre-season tournament, losing 4–2 on aggregate to Arema.

[28] After a poor run of results and fan protests against him, Persebaya dismissed Djadjang from coaching duties on 10 August 2019.
