First thing I thought when I heard this is that it's fucking terrible. Not from a "it's so offensive" way, from a "what a shit attempt to offend someone" kind of way. It's fucking embarrassing.
The worst part is that it's so forced and un-organic. There is no way that's an on the spot chant, because it isn't clear enough, you have to try and explain why what you're chanting is offensive and who it's aimed at. They've had to plan in advance, yet that is the best they could come up with. They've clearly met up online or in a pub and brainstormed what they could shout that would be clearly about his race, but not so offensive that they can possibly be able to make excuses for it not being racist. It's up there on a level of pathetic as the image of middle age Chelsea fans making Mourinho collages to take to the game, it's baffling.
