TURNING their backs on their team and the pitch, Manchester City fans once again made their feelings known this week.
But not in disgust - the supporters were celebrating their team's two goals against Birmingham City with the POZNAN.
Let's all do The Poznan
MAN CITY fans adopt terrace dance craze from lesser known Polish side
Britain's latest football crowd dance craze kicked off late last year when City played Polish side Lech Poznan in the Europa League - and saw how the Poles celebrated.
City fans are now copying them by turning away from the pitch, waving their scarves above their heads and bouncing up and down.
The Eastlands faithful also chant "Let's all do the Poznan".
Dozens of supporters have posted videos of the dance - also known as groundhopping - on YouTube and it's been caught by the TV cameras. But some confused fans have been visiting online football forums trying to identify the phenomenon.
A City disciple said: "It's the best celebration out there - you can feel the stand rocking. It started when we beat Poznan 3-1 last October."
Fans from other clubs, including West Ham, have been joining in the dance - and you can even get T-shirts showing the moves.
