The Premier League will most likely get 1 additional spot for the Champions League next season, depending on the achievements of the English clubs in all European competitions this season.
So the 5th position in the league shall join in the Champions League and the 6th position in the Europa League.
Manutd still has a big chance to take part in European competitions, because England has 5 clubs competing in all European competitions now.
With the new format, it will indeed be very possible if the EPL team does that it's just that for now I see is what if in the end there are new format rules when adding Champions League slots but this season Liverpool who are in competition in the EPL for the championship race (systematically in the top 4) and they become champions in the Europa Legaue because they are now competing in the quarter-finals and the big chance of winning is still very much there for now.
When the automatic slot for the Europa League champion (if Liverpool wins) whether there will indeed be additions from other clubs or not because in the end we can see it even become 6 slots if the new rules are 5 EPL clusters in the Champions League as well as the Europa League champion who is automatically included in the Champions League the following season.
Is this also possible or are only 5 slots still used?
Because if it is only 5 slots, I think all leagues are still possible, especially for last season we saw in La Liga who got 5 slots and the previous 2 seasons there were clubs from the Bundesliga who got it.
UEFA associations club coefficients ranking:
Italy 17.714 points
Germany 16.357 points
England 16.250 points
The 2 countries with the highest points will get 1 additional spot for the Champions League next season.
Currently there are 5 clubs from the Premier League still competing in all European competitions, while there are only 3 from Bundesliga.
UEFA rules only allow
a maximum of 5 clubs from each country to compete in the Champions League,
but these rules do not apply if,For example: Mancity won the Champions League but their position in the league at the end of the season was ranked 7th (1st to 5th UCL and 6th EL),
then there will be 6 representatives from the Premier League to join the Champions League next season including Mancity.
And if Mancity win the Champions League, and they finish in the top 5 (league) = England representatives will still be 5.
And if Liverpool wins the Europa League, it will be considered the same as the Mancity case above.
Because Liverpool will almost certainly be in the top 4 in the league at the end of the season.
So, it is still possible for 7 clubs from England to take part in the Champions League if Mancity wins UCL, Liverpool wins EL and both of the teams are not ranked in the top 5 (league)
