RB Leipzig announced on June 30 2026 that 46‑year‑old Cristian Fiél has joined as a new assistant coach – a clear expansion of Martin Demichelis' staff. The former Dynamo Dresden player and coach, dismissed by Hertha BSC in February 2025, will share daily preparation duties with Stefan Buck and Mariano Cambursano.

Who is Cristian Fiél?

Cristian Fiél, born 1977, spent almost a decade at Dynamo Dresden and later gathered coaching experience at several German clubs. After a brief stint at Hertha BSC, where he was let go in February 2025, he returns to Saxony to take the next step in Leipzig. His expertise lies in the attacking midfield, where he teaches tactical flexibility and game understanding.

Why does this matter for RB Leipzig?

The new assistant trio adds to Demichelis' already established group, which includes goalkeeper coach Frederik Gößling and Jan Zimmermann. Buck and Cambursano have already worked with Demichelis at Bayern Munich and River Plate, so Fiél will fit into an already cohesive system. Currently, RB Leipzig sit third in the Bundesliga with 65 points, 20 wins, 5 draws and 9 losses – a solid base for the title chase, even though the team trails Bayern Munich by 24 points.

What about the Japanese signing?

Alongside the coaching appointment, Leipzig announced the signing of 22‑year‑old forward Ota Yamamoto. The striker arrives from Kashiwa Reysol on a contract until 2031 but is immediately loaned to the Japanese affiliate RB Ōmiya Ardija. This move shows Leipzig's strategy of securing young talent long‑term while giving them playing time in a familiar environment.

What comes next?

Demichelis will plan training with Fiél, Buck and Cambursano for the upcoming matches, while the squad tries to recover after a 4‑1 loss to SC Freiburg on May 16 2026. The last five games present a mixed picture (LLWWL), with the most recent two defeats. Currently sidelined is Viggo Gebel, limiting attacking options further. Nevertheless, the goal remains clear: collect points to stay in the championship race.

Outlook

With Fiél on board, RB Leipzig can further refine its playing philosophy and boost offensive firepower. The blend of experienced assistants and young international talent could be the edge needed as the team aims to exceed the 66 goals scored this season while reducing the 47 conceded. The coming weeks will reveal whether the new coaching structure bears immediate fruit.
