The draw for the Champions League group stage takes place on Thursday in Istanbul.
Six British sides will be among the 32 teams drawn into eight groups of four in Europe’s premier club competition.
Here, the PA news agency looks at all the key information.
Who are the British teams in the draw?
English champions Manchester City are joined by the rest of last season’s top four in the Premier League – Liverpool, Chelsea and Tottenham. Scottish champions Celtic and fierce rivals Rangers are also involved this year.
Two teams from Scotland?
Yes, for the first time since the 2007-08 season, the Scottish Premiership will have two clubs in the group stage. Scotland’s improved UEFA coefficient ranking meant Celtic qualified automatically, while Rangers came through qualifiers against Union Saint Gilloise and PSV Eindhoven.
Can the British teams face each other?
Teams from the same league cannot meet in the group stage, but there is nothing to stop an English team being drawn against a Scottish opponent.
How does the draw work?
Clubs have been split into four pots, with one team from each making up a group. Pot one is made up of holders Real Madrid, the other champions of Europe’s biggest leagues and Europa League winners Eintracht Frankfurt.
