It’s largely become accepted wisdom that the bulk of Liverpool's successes and failures have been built on the smallest of margins in recent years.
And if Jordan Henderson's last-gasp, 25-yard curler had dropped inches lower, Jurgen Klopp will have been able to puff out his cheeks and move on from a taxing examination in west London with three precious points in the bag. The tone of the post-match inquest would certainly be less terse, at least.
The fact the skipper's arched effort only cannoned off the woodwork, however, means that Klopp and his staff will have to sift through the frustration and disappointment for over a week now until Crystal Palace visit Anfield on August 15. There is much to discuss behind the scenes.
