Manchester City fans “do the Poznan” because it’s become one of their main terrace celebrations: a collective, choreographed way to show unity and joy after a goal or a big moment in the game. It is not directly about the city of Poznań itself, but about a fan‑chant dance that originated with supporters of Polish club Lech Poznań and was later adopted by City.

What the Poznan actually is

The “Poznan” is a chant and physical move where fans:

  • turn their backs to the pitch,
  • link arms side‑by‑side,
  • then jump up and down together in rhythm.

It’s usually done after a goal or in a big away‑stadium moment, and it creates a striking visual of the entire stand “rocking” in unison.

How it spread to Man City

  • The tradition started in Poland with Lech Poznań supporters, where it was first used as a kind of protest‑style show of strength, still showing support for the team.
  • When Manchester City played Lech Poznań in the UEFA Europa League on 21 October 2010 , City fans saw the choreography and, despite a mixed first reaction, soon adopted it as their own.
  • The chant line “Let’s all do the Poznan, let’s all do the Poznan… Na na na na!” was coined by City fans, and the name stuck as a tribute to the Polish club that inspired it.

Why City still do it today

  • It’s now a core part of City’s fan “brand” and a ritual tied to that 2010‑era era, when the club was beginning its modern‑day trophy‑run.
  • Doing the Poznan helps build atmosphere, gives away fans a quick, visible way to show allegiance, and fits the image of City as a loud, organized, modern‑style support group in the Premier League.

In short, City do the Poznan because it’s a catchy, crowd‑binding dance that started in Poznań, Poland, and became a signature celebration for Manchester City fans around the world.
