A high percentage of football fans are biased idiots with no sense of proportion whatsoever. That's why football is a bit like pantomime. Boooooo. Hissssss. The 50/50 decision should have been give our way. No it should have been given our way. That ref is on your side. Oh no he isn't. Hissss. Boooo. He's behind you.
I saw a quote from a Liverpool fan yesterday, totally matter of fact, totally unchallenged by anyone. He said "Mo Salah is one of the biggest heros the Kop has ever had. But if he leave this summer he becomes the biggest mercenary traitor in the history of the club".
If he leave he just wants to leave you moron. There could be many different reasons why that is. I like to think that at City much of our fanbase is a lot more balanced than most other clubs. In the main we have accepted that players come and players go for their own reasons - ambition, location, game time, family etc and they don't suddenly need to become public enemy number one for having the temerity to change clubs.
