The league champions from UEFA’s seven top-ranked nations will be placed in pot one for the 2015-16 competition.
It could mean some of the biggest clubs in Europe clashing as early as the group stages.
The latest seeding rules will come as bad news for teams such as Arsenal and Manchester United, should they qualify for the Champions League but not win the Premier League or, in Arsenal’s case, not land the biggest prize in European football this season.
Both clubs have previously enjoyed top-seed status due to their high UEFA coefficient.
