I noticed it too, and that was just from the few shots of the crowd they showed on tv over here in the US. But take care fellow Blues, because as much as the Asian or Middle Eastern fan tends to stick out because of their appearance/language, and as much as we all hate the idea of plastic fan types with half and half scarves and zero loyalty or knowledge of the club they are "following", it is fair to say that not all of the foreign fans one sees at a match are a part of that demographic.
In fact, for some it may be one of the biggest days of their life, the achievement of a longtime goal to finally see their club in person. They may live and die with the club via satellite television and the OS. They may have paid those exhorbitant secondary prices and be sat right up front because they know that this is their one shot at it. Hell, even I , who have never set foot in England, felt that tinge of "ooh, they don't really belong" when I saw some of the above fans sat behind one of the corner flags.. Again, that's just from seeing the games on tv: I knew that they were "new", because it's not who I usually see there when the camera zooms in for corner kicks.. So if I feel it as a relatively recent fan then I know it must sting you lifers. But I have to step back and remind myself that they might be just like me: possibly a fan for only a few years, but nonetheless very informed, very passionate, and VERY excited to be there.
I would be able to blend in. Faking a Manc accent notwithstanding, I'm a white guy. I'd never be caught dead in a split scarf, and I at least know what a meat pie is (though I've never had a proper one). I doubt anything will be able to ruin my first match experience when it happens, but I will say that I hope to be welcomed with open arms, and it would hurt if the greater good of cheering on City together with the rest of you was cheapened by people sniggering at the weird foreign guy. My experience with other Blues on this continent has been that they are some of the nicest, most welcoming, and most knowledgable folks around. I have to believe the same must be mostly true in Manchester.
I guess what I'm saying is that I feel bad that these fans are subject to negativity because of the way they look. Assuming they have on City gear and don't act like complete fools, they should be given the benefit of the doubt, because as much as you are judging them, they are judging you too. Ostensibly, they are converts from a far away land and this may be their first time in church. greet them like a true believer and let god sort out the heretics. The good fans want desperately to be a part of a wonderful thing, and the bad ones won't last anyway.
