Yeah, I don't think there is a right or wrong.
Most top teams rest players in the cups.
It will always be a debatable issue.
Finishing top 4 has become more important than winning some of the cups. Again, its another debate.
The only thing I am dead against, is playing half a best team & half youngsters/subs.
You won't win the europa doing that & you just tire out your best players for no reason.
Either play our best team or all subs & youngsters.
Bur that's just my opinion. Poch might be right & we can win cups with half our best team.
I don't see it.
As for developing players, I am a big fan of sending players out on loan.
I don't think 3 or 4 cup games all season is anywhere near enough to develop.
I'd rather they had a season playing in the championship.
