England players including Mason Mount and Luke Shaw were ridiculed online after getting the words to the National Anthem wrong just before Monday's World Cup opener against Iran.
The anthem, which is now 'God Save the King' following the death of Queen Elizabeth II earlier this year, was sung before the match as is customary before all international fixtures - but the change appeared to catch a couple of England's players out.
Mount and Shaw were the unfortunate players who were in front of the camera during the anthem and were caught singing 'Queen' instead of 'King' in Qatar - which was promptly spotted by eagle-eyed fans online.
Monday's match marked the first time that 'God Save the King' had been sung at a World Cup since 1950 in Brazil following King Charles III ascension to the throne.
Mount and Shaw's mishap came just seconds before England's opening match of the 2022 World Cup in Qatar, where the Three Lions locked horns with Iran. The Three Lions headed in at the break 3-0 up courtesy of goals from Jude Bellingham, Bukayo Saka and Raheem Sterling.
Gareth Southgate insisted before the match that he was eager to "play on the front foot" against Carlos Queiroz's side and ditched his preferred five-man defence for the game at the Khalifa Stadium.

The build-up to the match was dominated by controversy over the 'OneLove' armband that England had insisted Harry Kane would wear ahead of the tournament in a bid to promote diversity and inclusion in Qatar, where same-sex relationships are outlawed.
But in a statement released on Monday morning, the FA said: "FIFA has been very clear that it will impose sporting sanctions if our captains wear the armbands on the field of play. As national federations, we can’t put our players in a position where they could face sporting sanctions including bookings, so we have asked the captains not to attempt to wear the armbands in FIFA World Cup games.
"We were prepared to pay fines that would normally apply to breaches of kit regulations and had a strong commitment to wearing the armband. However, we cannot put our players in the situation where they might be booked or even forced to leave the field of play.
"We are very frustrated by the FIFA decision which we believe is unprecedented – we wrote to FIFA in September informing them of our wish to wear the One Love armband to actively support inclusion in football, and had no response. Our players and coaches are disappointed – they are strong supporters of inclusion and will show support in other ways."
