Changes to Champions League rules agreed today could see Europe's top nations having up to five teams in UEFA's top club competition.
From 2015, the Europa League winners as well as the European champions will qualify automatically for the following season's Champions League, UEFA sources have confirmed.
But if the Europa League is won by an English club, they will not take the qualification place of a team finishing fourth in the Premier League - as happened to Tottenham last season when Chelsea won the Champions League but finished sixth.
The principle was agreed by UEFA's executive committee on Thursday and will be formally announced at the European governing body's Congress in London on Friday.
The move is designed to make the Europa League more attractive and to persuade clubs to take the competition more seriously.
The change to allow a maximum of five clubs also answers concerns from the European Clubs' Association who felt that the chances of the Europa League winners taking a place away from clubs qualifying via the domestic league was unacceptably high.
In the unlikely event of two clubs from the same country winning the Champions League and Europa League and both finishing outside of the domestic qualifying places, then those teams would still qualify for the Champions League but the side finishing fourth would miss out.
