The World Cup is finally here.After weeks anxiously waiting for the tournament to kick-off in Russia, football fans have got their wish, with Robbie Williams and Vladimir Putin leading the way at Luzhniki Stadium in Moscow.While the opening fixture of Russia v Saudi Arabia isn't exactly the high-profile affair of past World Cups - we were treated to Brazil v Croatia in 2014 - barely anyone could contain their excitement.Amazingly, Russia and Saudi are the two lowest ranked teams in the tournament.The Luzhniki looked mighty impressive ahead of kick-off and people were surprised at how good the opening ceremony was, with Williams proving a bit of a hit in the Russian Capital.However, there was one moment that got a lot of attention on Twitter, with the singer from Stoke-on Trent clearly flipping the bird at the camera during his performance.You can see the footage below.Pretty obvious, that.The clip went viral in a flash and England star Kyle Walker won Twitter with his post in response. Can England get a pass to the last-16 for this?

WALKER'S TWEET

Within eight minutes of the tweet being live, it had been retweeted over 1000 times and liked by 3000 fans.

If you're unsure of the context behind the tweet, then let us explain it to you.

Back in late 2017, Dele Alli picked up a one-match ban after being caught on camera brandishing his middle finger during a game v Slovakia.

After the incident went viral, Alli explained that it was directed at his old teammate Walker and not an opposing player or the referee.

Nice to see England players keeping their Twitter game strong on World Cup day.
