All the info you need to know ahead of Thursday's group stage ball-picking…
Europe's elite club competition is back – only this year it features some unlikely lads from the Premier League.
Leicester go straight into Pot One (see below for other Pot One teams) after winning England's top division last season, while Tottenham return to the competition for the first time since 2010/11 and may face some of the big boys thanks to their place in Pot Three.
The group stage draw will take place in Monaco at 5pm BST on this coming Thursday, August 25.
Meanwhile, all the clubs will be duking it out to secure a place in the final to be held on Saturday, June 3 at the National Stadium of Wales, Cardiff (otherwise known as the Principality Stadium, or better yet the Millennium Stadium).

Pot One: Real Madrid (ESP, holders), Barcelona (ESP), Leicester City (ENG), Bayern Munich (GER), Juventus (ITA), Benfica (POR), Paris Saint-Germain (FRA), CSKA (RUS)

Who can play who?
No team can play a club from their own league at this stage. Following a decision by the UEFA Executive Committee, Ukrainian and Russian teams can't be drawn against each other either. Probably for the best, that.
