The club got the BVB, Leipzig and Leverkusen to give up on 20 million EUR together of the Champions League and give it to the 3rd league and the womens' Bundesliga.

But the EPL lacks a club that has the influence to get the others to act like this. So each club might have their own charity objects in the local communities were they help - but nothing substantial that really helps the lower leagues.
