Former Liverpool goalkeeper Kamil Grabara seemed to take a swipe at FC Copenhagen team-mate Mat Ryan after his mistake led to Australia's exit at the World Cup.
Australia were beaten 2-1 by Argentina after goals from Lionel Messi and Julian Alvarez sealed a quarter-final showdown against Virgil van Dijk 's Netherlands side.
There was little ex-Brighton and Arsenal keeper Ryan could do about Messi's brilliant opener. But it was his poor touch that led to Manchester City striker Alvarez doubling Argentina's advantage.
