Manchester City had many dubious decisions going their way on Saturday. City should have gotten at least one red card and a penalty against them, but they didn't and there were no talks about it.
The media all of a sudden went blind but 24 hours later, a clear and obvious foul happened that benefited Arsenal, everyone and their attack dogs are on it.
It is obvious that it is okay when it benefits Arsenal's opponents but it is a big issue when it benefits Arsenal.
