UEFA have moved today to make the Champions League a more literal interpretation of the competition by changing the seeding to Pot 1 starting in 2015-16.
BREAKING: UEFA confirm the Champions League seeding system will change for next season
— MailOnline Sport (@MailSport) October 9, 2014
The champions from the top seven European leagues (Spain, England, Germany, Italy, Portugal, France, Russia) plus the current title holders from the previous Champions League will be the eight Pot 1 clubs. From there, seeding will commence as usual using the same coefficients that have been in place.
This will affect Arsenal in the sense that they must win either the Premier League or Champions League in order to secure a Pot 1 seeding, which they've grown accustomed to for quite some time. It also means that we'll be seeing a much stronger Pot 2 than we've previously seen, with any number of Chelsea, Manchester City, Real Madrid, Barcelona, Atletico Madrid, Borussia Dortmund, Bayer Leverkusen occupying those spots.
What hasn't really been determined yet, or at least what I can find on the interwebs, is when the Champions League title holder is also a champion from one of the top seven European leagues. It has been speculated that the club with the highest coefficient will take the last Pot 1 spot, but until that's confirmed it's still undetermined at this time.
Either way, regardless of your thoughts on this, it'll be curious to see how next season's Champions League pots look like and how radically different they are from what we've seen in the past.
