Comparing city and PSG's fan is a joke, please don't insult us.
Until 2010, our ultras were reputated to be top level in Europe, just watch how famous was the kop of boulogne for example.
Then all ultras were banned and we lost our atmosphere until last year when ultras from Auteuil were finally allowed to come back.
Our stadium is always full, even in small games the atmosphere is better than Old Trafford or Anfield in CL games.
Regarding the history, please note that our club was created in 1970, we're a young club, and still, we are the most titled club in Ligue 1 and we were one of the best european club in the late 90's winning the C2 then.
Finally, i want to make a point about L1, which will never be able to overcome structural injustice compared to other european clubs:
1) The DNCG, French club can't go to far in debt. Compare that with Clubs like RM or Barcelona who used to be deeply in debt to sustain their growth.
2) Taxes. "In France, taxes for a player whose gross annual salary is 600,000 euros are five times higher than those paid in the United Kingdom, 15 times higher than in Germany and 66 times higher than in Spain"
That's why i always laugh when some foreigners talk about FFP, there is no Fairplay when PSG pays more taxes(170m€ p.a) than RM, Barcelona and Bayern alltogether.
I am not saying that our club is a european giant, or that we're close to being one, but we don't come from nowere, we always have been one of the top clubs in France.
