How it works
The 32 qualifiers have been divided into four pots based on the Uefa coefficients, which are in turn decided by a mixture of the team's own performance in Europe over the past five seasons, as well as the strength of their country's league.
The Champions League group stage comprises eight pools of four teams: consequently, a team from each pot is drawn and placed into one of the eight groups available. This is done by pot and not "one at a time": that is to say, all the teams from pot one will be placed into a group, and then pot two, and so on down to the fourth and final pot.
There are some restrictions, though. Teams from the same national association cannot be drawn together, and even prior to that there will be two 'sets' of groups decided for the purpose of television rights. For example, the four teams from Spain cannot all be drawn in the same set.
The Champions League Group Stage pots for 2014-15 are as follows:
What to look out for
- The Group of Death: Just how hard can the Champions League be? Consider the strength of a group such as the following: Real Madrid, Borussia Dortmund, Liverpool and Roma ... Or how about Bayern Munich, Manchester City, Ajax and Monaco?
- Recent Reunions: Real Madrid proved to be too strong for Borussia Dortmund last season and may well relish a re-match against their German opponents. Meanwhile, Paris Saint-Germain's European adventure came to an end against Chelsea in 2013-14 and the Ligue 1 champions will be keen to get a shot at revenge.
