Randomly getting myself wound up with refs recently, it clicked with me about the lack of background checking when they state the teams they support. Now, they all will follow a team, the fact you get into refereeing will be from a love and joy of football. Any ref declaring they don't have a team needs immediately investigating.
Then you get the likes of Alty, a lad from Wythenshawe, a place I have grown up myself where you are either a red or blue. At what point do you choose non leage Alty when your family support United. You just don't do you. I have also lived in Altrincham and attended games there and whilst there will be a few hardcore, the rest are City and United fans taking in a game of footy.
If you want to be a ref at the top of football, you simply cannot declare you support a top side, otherwise your progress will be limited. Taking into account United and Liverpool especially have gazillion fans worldwide, how is it you don't hear of any refs in the lower leagues supporting them? You also don't hear of a fantastic referee in the lower leagues, who unfortunately cannot ref at a higher level due to the team they support. It is surely impossible that the so called best referees in England, all support lower league sides. It never will but it needs looking into. I don't get why we don't recruit oversees referees, they are a better standard and cuts out any accusations of favouring teams they support.
