The 2018 FIFA World Cup got off to a superb start as hosts Russia beat Saudi Arabia in the opening game in Moscow on Thursday. After an opening ceremony that saw Robbie Williams entertain the crowd, Russia were pumped up for the game as the Saudis were blown away in what turned out to be a pretty one-sided game.Yury Gazinsky opened the scoring for the hosts in the 12th minute before playmaker Alan Dzagoev came off injured clutching his hamstring. However, he wasn't missed as substitute Denis Cheryshev doubled the lead with a sublime move.Artem Dzyuba made it 3-0 in the second half before Cheryshev made it 4-0 with a sublime outside-of-the-boot strike in stoppage time. To cap off a five-star performance, Russia made it 5-0 when Aleksandr Golovin curled in a free0kick with what was the last kick of the game.Here's how Twitter reacted to the game.The 2018 FIFA #WorldCup is currently averaging five goals per game!

Couldn't wish for more obliging opponents in #ksa but crushing win for hosts great way to start #WorldCup— Adam Gray (@AdamGray1250) June 14, 2018Congratulations, Denis Cheryshev, on your impending €110 million return to Real Madrid.— Tom Williams (@tomwfootball) June 14, 2018Mohamed Salah watching the #KSA defence like...#WorldCup #bbcworldcup pic.twitter.com/9B90zkkjkN— Match of the Day (@BBCMOTD) June 14, 2018Until today, Denis Cheryshev had never scored for Russia. After this game, he is now one goal behind Cristiano Ronaldo (in the #WorldCup only). #RUSKSA— Rohith Nair (@RohithNair) June 14, 2018Russia vs Saudi Arabia pic.twitter.com/MvovYK0Cxc— Troll Football (@TrollFootball) June 14, 2018That’s a huge blow for Russia. All the talk before the tournament has been about Golovin but Dzagoev is every bit as good. You can’t say much for Russia’s midfield generally so that’s a real shame. #RUSSAU— Matt Scott (@Matt5cott) June 14, 2018Excited for the World Cup opener between Russia and Saudi Arabia. It's a crucial game; the winner gets to run U.S. foreign policy.— Adam Serwer 🍝 (@AdamSerwer) June 14, 2018Aleksandr Golovin (1996) is the first goalscorer for #RUS at a #WorldCup who is born after the dissolution of the Soviet Union in December 1991. #RUSKSA— Gracenote Live (@GracenoteLive) June 14, 2018Goalovin— Poorly Drawn Arsenal (@cantdrawarsenal) June 14, 2018✅ Russia 5-0 Saudi Arabia🇷🇺 Win On Home Soil🥅 Clean Sheet👏 3 Points⚽️ 5 Goals🔝 Top Of The Group😎 The Perfect Start 🍷 pic.twitter.com/fPowwtV8Oi— SPORF (@Sporf) June 14, 2018
