We see many strange decisions nowadays, probably due to the amount of cameras at matches,but the standard of the linesman hasn't made much improvement if this small quote suggests.
Gordon Banks talking about a FA cup semi final versus Arsenal in the 70's.
Stoke lost the replay, just as they did against the same opposition a year later - again under questionable circumstances when the linesman apparently mistook a touchline programme seller for a defender, allowing Radford to race clear and score the winner despite being a long way offside
Amazing.
