I don't know how the non-selling thing would ever work anyway unless players could leave on a free transfer.The original story being reported was that Barca couldn't buy or sell any players. The selling part now seems to have been removed from the articles.
That's just the one we know of right now, I believe it'll end up in a lighter sentence or a delay
Only just seen this, but the ban was for U18s and no-one else. Even if it came into effect/stays in effect it would have little bearing on the day-to-day running of the club.
