Champions League powers Bayern Munich and Arsenal will find out Friday which opponent they must beat to reach the lucrative group stage.

Bayern and Arsenal, Champions League runners-up in 2010 and 2006, respectively, must win a tense home-and-away playoff this month to secure the minimum ?20 million ($28.6 million) payment from UEFA that's guaranteed to German and English clubs playing in football's most-watched club competition.

Benfica, Lyon and Villarreal join Bayern and Arsenal as the seeds in the 10-team draw for non-champions from Europe's stronger leagues.

In a separate draw, league winners from 10 mid-ranked countries will be paired for ties to decide five more places in the 32-team group stage.
