It has been presented very poorly with some questionable inclusions but the idea itself is very good in my opinion
The likes of Barcelona, Sevilla, Madrid have seen massive improvements by having their B sides in the division below theirs. It gives youngsters the chance to compete regularly at a higher level and therefore improve alot quicker. (Even League 1 is a big step up from the u21 leagues)
Each side has to have 20 home grown players out of the 25 so it would only benefit future English players, but i can also see why lower league clubs wouldn't want this to happen
Nowhere in the world is the lower leagues as competitive and as watched as in England
On a personal note: I would love to see the LFC youngsters in the lower leagues
