It's a brilliant option.
Means you can now clear out your team at the end of each season keeping maybe 5 'scout' players and 5 or 6 Academy 1* and 2* and still have cash to refill at the start of next season with 5* players a nice low level Cup and league opponent draw.
Did it last season and for the first time in 30 seasons I've got a cup draw with teams my level!!!!!
