I think the other thing is too that the Ultras have so much power in these clubs that extends way beyond just the singing that its easier to build on top of this eg have an area/pyro/flags etc - I noticed in Lille a couple of them were constantly over the hoardings at the front for example which you would never get in England!
Fair play to the lads in 1897, one thing it will do is extend that holte singing into other areas and keep going
Also replying to comment above, agree we can be to nice - Couple of fouls yesterday where we should have been up off our feet calling for yellows, im convinced it influences refs
