We are talking about the possibility of the Premier League to have an extra quota for the Champions League next season. But still the interesting part is the total number of CL titles achieve by English teams is like the same as Real Madrid's winning number. 
This shows that PL teams aren't the most successful ones despite playing in the most prestigious European league according to statistics. I don't know this additional quota would help change this data for their advantage either. But one thing is sure that they will be more dominant in numbers in the group stage compared to other European leagues in this case. There is nothing guaranteed yet though. Let's see if they can earn this first.
