League of Legends Worlds Finals live: Korea's T1 and China's BLG face off in London

What's going to happen? The Opening Ceremony is set to kick off at 14:00 GMT.

After that, the showdown begins between the final contenders, China's BLG (Bilibili Gaming) and South Korea's T1.

It's a best-of-five format, with each game typically lasting between 20 and 45 minutes.

Last year, there was about a 15-minute break between games.

A team need to win three games to take the championship.

After that, they will be crowned at the award ceremony.

'Iâ€TMve dreamt about it for years'Jacqueline Howard Live reporter, reporting from the O2 Arena

Iâ€TMm here at the O2 Arena today alongside Andrew and roughly 20,000 League of Legends fans.

The level of enthusiasm really is comparable to a major football final â€" everyone is kitted out in support of their favourite team, and the excited chatter regularly transforms into enormous chants.

Among the fans here is Yuxu, who has travelled down from Glasgow to be here. She is handing out art sheâ€TMs made of BLG players to any fans she spots.

It comes as no surprise that she says sheâ€TMs confident of a BLG win today.

I've also ran into Zhang Changhui, who is down from Edinburgh. He is part of a group that has brought a massive BLG flag for fans to sign.

And I've met Lena and Moritz, who've travelled from Austria to be here today.

Theyâ€TMre diehard T1 fans who are thrilled to have the opportunity to be part of the crowd supporting their favourite team. "Iâ€TMve dreamt about it for years," Moritz tells me.

A warm welcome during an †̃esports winterâ€TMAndrew Rogers BBC Newsbeat, reporting from the O2 Arena

Hello and thank you for joining us as we cover the very exciting finals of League of Legends Worlds.

Thereâ€TMs no doubt that people here are hyped. Everywhere you look, fans are wearing shirts of their favourite teams in the final: BLG from China, and more often, Koreaâ€TMs T1.

Politicians and organisers are keen to highlight the economic benefits of this event, and it will undoubtedly provide a boost as people travel in from across the UK and the world. Tickets sold out in minutes.

But itâ€TMs not all good news. Some have called the last few years an "esports winter", because so many teams and tournaments have run into financial troubles and shut down. Arguably, the UKâ€TMs esports scene was more vibrant a decade ago, with more teams and more mid-sized events. Since then, money has dried up.

So while bringing Worlds to the UK is a massive vote of confidence, teams and organisers of smaller competitions will be hoping this isnâ€TMt just a flash in the pan.

What is the League of Legends World Championships? League of Legends (LoL) is a multiplayer game in which 10 players go head-to-head in a 5v5 match, competing to be the first to destroy the opposing teamâ€TMs base.

Launched in 2009, it has since hooked over 100 million players from more than 145 countries, according to its developer, Riot Games.

There are competitive leagues and championships across the globe, including in North America, Latin America, China, and South Korea. It's much like football, with a barrage of international and national competitions celebrated by millions of fans.

Among these events, the grandest is the World Championships (Worlds).

This event is truly top-tier - it's the world's most popular esports tournament, boasting a peak of 6.4 million viewers last year, according to Statista.

And for the first time ever, the finals are being held in London!
