technology did not go wrong at Huddersfield on Saturday. Humans did. Ruling Juan Mata onside was not a clear and obvious mistake. Yet video assistant referee Neil Swarbrick still determined to get involved, giving him offside by little more than the hairs on a kneecap. Invariably, when VAR causes controversy it is its application by humans that is at fault. Poor referees will be poor video assistants, too. Swarbrick should not have got involved.
