Gonzalo Higuain's stunning volley for Argentina left many viewers with their jaws firmly on the floor - but his coach Alejandro Sabella went one step further.

The Napoli striker unleashed a stunning strike onto the top of crossbar with Argentina leading 1-0 against Belgium, much to the agony of La Albiceleste fans who were desperate to get to the semi-finals.

But none more so than Sabella, who simply could not contain his emotions.

The 59-year-old was hoping his striker could put the chance away to give his side a two-goal cushion and, while most coaches would perhaps opt for a head-in-hands gesture, Sabella bizarrely gave the illusion that he was fainting.

Argentina did eventually progress to the semi-finals thanks to Higuain's superb volley.

Let's hope for Sabella's sake there's not a penalty shootout.
