Like the other candidates have said 5th would be a reasonable goal for this season. Will we try to be better, of course, but 5th would be a decent season.
As for JR it's something I mean to look into, from all the info I've ever gathered/heard it seems like a waste(for the most part, obviously some is needed to maintain diversity). But I've just recently heard that Poland alway has high JR on their U21/NT players(sometimes higher than their JS), and it's something I mean to look into.
