Very nice topic, a joy to read!
It has been a few editions ago that I had a Athletic-save (back when Aduriz was their main man upfront). Was very fun and after reading here I am tempted to do one again.
A question though; do you guys had any luck getting good newgens/regens from the French Basque clubs? So is it worth loading up those leagues when starting up a new game and do you guys actively scout these clubs?
