Is this not a reduction from 6 players now down to 1?

It is saying that you must have 1 development player in your "matchday" squad cnat think of any team in the country that would put out 6 in a matchday squad
Ahh read it too quick, the 6 was for the squad as a whole picked or not. Hardly pulls up any trees, with 7 subs and probably most clubs would do this at some point for some match day experience anyway?
