Draw simulated
We know the basics of the draw after last year's revamp. Each side will be drawn against two teams from each pot - but cannot be selected to face teams from their own country.
How will that work in practice? Take a look at our simulated draw to see how things could look.
Prize money
It's no secret that being in the Champions League each year is a huge financial boost for teams at the top. But how much will they be earning?
Well, just for making this stage last year teams were awarded more than £15.5million! You can find a full breakdown of the sums here.
What it's all about
But who will be the one left standing at the end of the season?
PSG are the favourites following their success in Munich against Inter, but can they go back-to-back? Or will an English team be able to get their hands on the trophy in Budapest next year? Only time will tell...
Pots confirmed
The draw is set to kick off around 5pm BST. So wherever you are in the world, you can try and work out what time it starts for you!
Apart from that, the pots have already been confirmed, so here are the potential teams who could face each other.
