They could stop the game and the ref ask each group of fans pantomime style.
e.g. “was it offside”
Home fans all together “YES IT WAS”
Away fans “OH NO IT WASN’T”
This type of arbitration could also lead to more co-ordinated booing of the officials
I'm another vote to keep Eccles where he is. I thought Saturday was by far his best game yet. Confidence is a huge part of development. He made one or two minor mistakes in the game. No more than anyone else. I thought he deserved M.OM.
