Rather than headline City's problems in taking penalties, perhaps we should look at how the ref or linesman managed to miss the goalkeeper's movement off his line?
I wonder what position the linesmen were adopting?
If that was against Utd, then there'd be an inquest. It would be all over the BBC. Questions asked. With the result that next time a ref and his officials did a Man Utd game they would be under pressure. That's the background to refereeing City, Man Utd and Liverpool games. The officials don't feel pressure when we are playing, but when its Man Utd or Liverpool they know any decision against these sides will bring with it heavy scrutiny.
I don't believe the game is bent but I do believe that refereeing is biased through pressure.
