The Overwatch League officially begins on January 10 next year, but you don't have that long to wait if you're looking for Overwatch esports action.

As a warm up to the start of the season, there will be exhibition preseason matches starting on December 6 featuring all 12 teams.

On Wednesday, December 6 and Thursday, December 7, each team will play one game, and the results will determine the schedule for the rest of the week.

The Overwatch League season begins on January 10, with preseason games from December 6

The London Spitfire started up a Twitter dispute with their preseason opponents LA Gladiators

The Los Angeles Gladiators responded with their own video, asking who people would back

If you're in the UK though, these games will be very late at night, and the time difference means the first games will technically be on Thursday and Friday.

The following two days will have games based on the winners and losers from the first round.

December 6 schedule 4pm PST (12am December 7 GMT): Florida Mayhem v Philadelphia Fusion 6pm PST (2am December 7 GMT): LA Valiant v San Francisco Shock 8pm PST (4am December 7 GMT): Seoul Dynasty v Shanghai Dragons Advertisement

December 7 schedule 2pm PST (10pm GMT): LA Gladiators vs London Spitfire 4pm PST (12am December 8 GMT) Dallas Fuel vs Houston Outlaws 6pm PST (2am December 8 GMT) New York Excelsior v Boston Uprising Advertisement

Some of the teams are already very active on social media, following the official announcement of all the teams and their logos over the past month.

Particularly vocal are the Los Angeles Gladiators and the London Spitfire, who will be facing each other in preseason.

The two won't be facing each other too often when the Overwatch League season begins as they are in different divisions, but that didn't stop them engaging in a small Twitter dispute.

London Spitfire fired the first shot, uploading a video featuring actual spitfires shooting down planes with the Gladiators' logo on them.

We are ready to #TakeOff and face @LAGladiators on December 7th! Make sure to secure your tickets for the show!

The Gladiators responded with a video of their own, which cut between the official Overwatch animated shorts for Reinhardt and Tracer, the heroes which the two teams have chosen as their mascots.

The video makes it seem as though Reinhardt is heroic and charging into danger, while Tracer is running away. The video ends with the question 'Who will you stand behind?'

The accompanying Tweet asked 'Did you really want to start this war, Spitfire? Let's see how it ends.'

London Spitfire responded to the video with a simple animated gif of a Tracer killing a Reinhardt in an Overwatch game.

Other teams were a little more civil. Florida Mayhem Tweeted out the schedule, saying 'You know what they say... Save the best for first!'

Mayhem will be facing off against Philadelphia Fusion in the first game of the preseason.

San Francisco Shock were friendly towards their Atlantic League rivals Los Angeles Valiant too.

Preseason tickets are now available!

There are two teams from Texas in the upcoming Overwatch League, the Dallas Fuel and the Houston Outlaws.

They will be facing each other during preseason, but they'll actually be in different divisions for the Overwatch League. They'll still have a healthy rivalry though.

It's safe to say the results of these preseason matches will only serve to grow these rivalries, and it'll be exciting to see what else the teams have in store over the coming months.
