As always, there are 32 teams taking part at this stage of the competition, with the draw splitting them into eight groups of four from four seeded pots.

The first pot always contains the reigning champions - in this case Real Madrid - plus the title winners from each of the seven highest-ranked leagues in Europe.

Given Spain are among the top seven and Real are already included, that means the eighth country is also represented this season, with Ukrainian team Shakhtar Donetsk placed among the leaders.

Pots two, three and four are based purely on coefficients calculated using points gathered in European fixtures over the last five seasons, with more recent results carrying more weight.
