We're all backing City against Chelsea, but there's another face-off taking place at the Etihad Stadium today: Team Santa v Team Elf!
We've got two Christmas jumpers for you to choose between this year, one Santa and one Elf themed. Vote here for your favourite. https://www.mancity.com/en/fans-and-community/fans/festive-face-off
Keep your eyes peeled and you'll see the jumpers all around the stadium!
The Supporter Services team will have them on, while the guests and bands at City Square will be choosing their favourite jumper design.
There will be a giant snow globe at the top of Joe Mercer way, where fans can climb in and recreate the Santa v Elf face-off image.
The team that receives the most votes will be crowned the winner on Christmas Day. One person who votes for the winning side will be picked at random to present the Festive Face Off trophy to the winning captain.
To keep the festive theme going, our Christmas cards will be on sale at the stadium store. They are priced at just £1 and the proceeds will go to City in the Community.
