England's exit from the European Championship at the hands of Iceland was not only a shock to the nation but was also the United Kingdom's most tweeted-about sporting moment of the year.
Wayne Rooney gave England the perfect start to the Euro 2016 last-16 clash when he scored from the penalty spot after four minutes, but goals from Ragnar Sigurdsson and Kolbeinn Sigthorsson sent Roy Hodgson's men to one of the most humiliating defeats in English football history, prompting Hodgson to immediately tender his resignation.
It sent social media users into a frenzy in the UK, with a record 128,000 tweets-per-minute - 21,000 more than when Leicester clinched the Premier League title after Tottenham and Chelsea drew 2-2 at Stamford Bridge to hand the crown to Claudio Ranieri's men.
Daniel Sturridge's dramatic injury-time winner to give England a 2-1 win over Wales in their group stage clash at Euro 2016 also set pulses racing with 77,000 tweets-per-minute, which was announced as the UK's third most tweeted-about sporting moment in figures released by Twitter's '#ThisHappened'.
All of the top 10 sporting moments of the year came in football, with seven of the top moments coming during Euro 2016.
Perhaps unsurprisingly, Rio 2016 was the top trending sports event of the year globally as Team GB brought home a record total of 67 medals - including 27 golds - with Euro 2016 and Super Bowl 50 rounding off the top three.
Leicester's Premier League title win was the most retweeted event of the year with the club's tweet declaring themselves "Champions of England" garnering 396,000 retweets, 139,000 ahead of Muhammad Ali's official account remembering the boxer.
Zlatan Ibrahimovic confirming his move to Manchester United attracted 222,000 as the third most retweeted message, while UFC fighter Conor McGregor suggesting he was retiring also piqued interest in seventh place with 161,000 retweets.
Chelsea's 4-0 win over Manchester United in October is the most discussed Premier League game of the season so far as 1.8million tweets were posted, with N'Golo Kante's first goal in a Chelsea shirt the most-tweeted moment.
Manchester United were the top trending football club of the year ahead of Liverpool and Leicester but it was not all about the Premier League, with Newcastle (fifth), Aston Villa (seventh) and Leeds (ninth) all cracking the top 10.
