I just watched highlights of the NYCFC v Chicago Fire game and saw an example of why you have to retreat to your goal line upon calling “Away”.
Like all good goalkeepers, Josh Saunders’ original thought is to claim the cross. Upon assessing the flight of the ball, he elects to call “Away” and gives responsibility to his defenders.
Goalkeepers should ensure they get back on their line so they can react if the defenders do not get to the ball first.
Having watched this spectacular save by Joe Hart, you can see what can be achieved with that extra split second reaction time if you stay on your line.
