Yeah, but they would take the place of some other established club. There is life beyond the Premier League. If they started off in the very lowest and worked up, then fair enough. But what would happen if we drew Everton B in the cup?
Terrible idea. Just wouldn't work. It would just allow the clubs with money to harvest all the talent, rather than loan out players for competetive football to clubs in the lower leagues who can only survive throught the loan deals.
Why does it work in Spain then?
I'm pretty sure if they start from the beginning like every team did its fair. I'd have Man City B rather than Walsall mate or Plymouth which will allow us to develop players better and become successful as a nation.
