Think you know your football? Can you spot the best performers during a match before anyone else?
Once the starting line-ups appear (one hour before kick off) choose the three players who you think will perform best during the game, either for both teams or just for the one you support.
During the match, the Twelve Bot will crunch the numbers and everything the players do will be awarded points. You will see how you are doing compared to your friends. If the players you choose aren’t doing the job then you can change them live during play.
Before the game we will put up a link so you can follow Igor and Roger commentary on CBS. If you want a few tips about who is on form before the match then check out our match preview by Solomon Fowowe.
You can bait us and generally show off how well you are doing using #ChallengeTwelve and the @twelve_football Twitter account.
Prize: Last but not least, we will send a signed copy of David Sumpter’s book Soccermatics to the person with the highest points at the end of the game for Arsenal. Chelsea fans, you’ll have to wait until later in the season for your chance. If no-one beats David he will keep his book!
