An opera singer, a middle finger, and Putin's speech: All the best photos from the 2018 World Cup opening ceremony

This is the official 2018 FIFA World Cup opening ceremony. The view from above doesn't look too shabby…

…and a close-up of the action looks even more impressive.

English singer Robbie Williams was a focal point of the World Cup opening ceremony. Before the event, he told ITV that, when he was a boy, he dreamed of performing in the tournament as a soccer player and that now he's an adult, he'll have to settle for singing at one instead.

Williams got the party started with his smash hit single 'Let Me Entertain You,' rather than 'Party Like a Russian,' which was criticised in Russia for its stereotyping lyrics. He probably made the right song choice on Thursday.

Williams, who also sung 'Feel,' was joined by Russian opera singer Aida Garifullina, who joined him for a duet of 'Angels.'

There was lots to look at, including gymnastics and pyrotechnics.

There was even an appearance from former Brazil striker Ronaldo, who won the World Cup in 1994 and 2002.

In the middle of a jig, Williams flipped his middle finger at the camera. It is not currently known who the gesture was aimed at.

Once the ceremony was over, Russian president Vladimir Putin stepped onto the dais to deliver a speech.

Putin's speech was put up on the big screen and broadcast to the billions watching around the world.

Once Putin and Williams returned to their seats there was only one thing left to do — let the games begin!
