Anyone watching the Man U game have a view flag didn't go up until after the Wolfsberg players had run over and spoken to the linesman. That surely can't be right can it Mata was in an offside position though
It's what there taught Farnham, Play to the whistle and complain after. The players are wrong if they do and wrong if they don't.
The linesman signalled to the ref that he was offside instantly but needed to check with the ref to see if he was interfering with play. As soon as the ref said yes he was the linesman put his flag up. The players did run over complaining but it didn't influence anyone's decision.
