This is exactly why refs are terrified of giving us anything, and much more comfortable ruling against us. Anything that goes out way is scrutinized to absurd degrees while anything that goes against us is swept under the rug, often not even given a replay during the game. It's infuriating, and it has been going on for years. Refs know that anything they give us will be called into question, and it absolutely affects their decisionmaking.
Heard many people calling this a "blatant handball." Even when zoomed in 400% and viewed from every possible angle, you literally cannot see if there's a touch; and even if there is one, it's a brush of a fingertip that doesn't change anything at all. Nevertheless, "omg blatant handball, refs are always helping United!" All the while, our players get kicked to pieces week in week out, and our goals are put under a microscope to look for any possible fault.
