Matchday One of the 2018 FIFA World Cup is officially over with Poland and Senegal being the last teams to play their opening fixture of the group stage.
38 goals were scored across the first 16 fixtures however the opening round hasn't escaped controversy, with the VAR taking just five games to make a huge mark when it was used to rule a penalty in favour of France. The 2018 World Cup is also becoming known as the World Cup of penalties, with 9 being awarded in the opening round; 7 of which were converted.
Here's a look through how each Group fared through Matchday One
Host nation Russia got off to a blistering start, crushing Saudi Arabia 5-0 thanks to a double from Denis Cheryshev in front of a beaming Vladimir Putin. Uruguay and Egypt battled out a tough contest for 90 minutes however the South Americans stole the three points at the end with a late Jose Gimenez goal as the Egyptians struggled without Mo Salah.
Saudi Arabia 0
Morocco were unlucky not to convert any of their chances against Iran in their first World Cup match since 1998. Their inability to take advantage cost them as Iran snatched a late winner through an own goal. A Cristiano Ronaldo hattrick threatened to steal the show in an incredible 3-3 draw with Spain. The tides turned on multiple occasions throughout the game but it was CR7's free kick that resulted in a draw and one of the best games in recent World Cup history.
The VAR made an early impact when it ruled that Josh Risdon clipped Antoine Griezmann in the box. It was used again to draw Australia level after Samuel Umtiti handled the ball. Pogba's winner dealt a harsh blow to a Socceroos side who fought endlessly above their weight to the final whistle. Peru were left to rue a missed penalty when Yussuf Poulsen scored the only goal in a victory for Denmark.
Argentina dominated the stats in their match with Iceland however they couldn't escape with a win after Sergio Aguero's opener was crossed out by Alfred Finnbogason. Lionel Messi had a huge chance to take the three points with a penalty however he was thwarted part-time film director Hannes Halldorsson. Croatia got off to a perfect start with a routine 2-0 win over Nigeria.
Brazil failed to win their opening match of a World Cup for the first time since 1978. A stunning Philippe Coutinho strike was cancelled out by Steven Zuber with Neymar largely kept out of the game. Serbia got off to a strong start with a 1-0 win over Costa Rica. Their only goal came from a brilliant Aleksandar Kolarov free-kick.
Costa Rica 0
The World Champions were stunned in their opening fixture as a goal from young gun Hirving Lozano was enough to shoot Mexico to a monumental 1-0 win over Germany. Sweden also sealed a narrow 1-0 win in their opening match, over South Korea. The Swedes were awarded a penalty in the 65th minute which captain Andreas Granqvist calmly slotted.
South Korea 0
Belgium got their World Cup campaign off to a cruisy start by disposing of Panama 3-0 courtesy of a Romelu Lukaku double and a spectacular strike by Dries Mertens despite struggling to score in the first half. England managed to scrape past Tunisia with a late 2-1 win after having trouble breaking through the defence of the African side. Harry Kane was unsurprisingly the saviour for the Three Lions.
Japan and Senegal were listed as the underdogs to make it out of this group however they produced shock wins over Colombia and Poland, respectively. Colombia suffered the second quickest red card in World Cup history as an early Japan penalty opened the scoring en route to a 2-1 win. Grzegorz Krychowiak had an up and down game, with his back-pass leading to Senegal's second before he scored Poland's consolation goal in a 2-1 loss.
