WHAT IS STAR SIXES?
Billed as 'the first ever competitive world football tournament for iconic former international players', Star Sixes brings together a host of big names in London.
The tournament will see 12 international teams do battle across four days, with the winners crowned as Star Sixes champions on Sunday night.
England, Spain and Brazil are just three of the countries involved in the group stage, which will be played across Thursday and Friday evening and Saturday lunchtime.
Squads of 10 will compete, although, as the name suggests, the event will be a six-a-side format with rolling substitutes.

Each team will have a captain who also acts as the manager, deciding who starts each game and who goes off and comes on.
Group stage matches will be played over 20 minutes, with each of the knockout games consisting of two 15-minute halves with a short break.
Star Sixes is already scheduled to return to the O2 in the summer of 2019, with six-team regional tournaments also set to take place before then.

HOW DOES THE TOURNAMENT WORK?
The 12 teams have been drawn into three groups of four. Each side will play every team in their group, with the top two progressing to the quarter-finals.
The other two quarter-final spots will be filled by the two best third-placed teams, meaning four teams will be heading home after the group stage.
The last eight will clash on Saturday evening, with four teams progressing to Sunday's semi-finals. The losers in each of these games will take part in a third-place play-off, with the winners going on to compete for the Star Sixes trophy.
Group stage matches will be 20 minutes long, with all knockout games played over 30 minutes with a short break.
Games are six-a-side with rolling substitutions and there is no head-height rule. There is also no restriction on player movement, while drawn knockout games will be decided by a penalty shootout.
