Participation of B Team in Spanish League

[junwenteh]

Hi,

I would like to start a game in Spanish League, and noticed that the lower leagues have clubs with or without B Team (their version of reserves). Some B Teams are so low in reputation that they are just place holder and do not participate in any competative leagues (not in Spanish B2 Leagues, nor any known lower leagues in the game).

My question: Do teams without B Teams generate their own B team affiliates when they become reputable enough, or that these teams without B teams will never have a B-side in the future? Otherwise, do existing B-sides hop into the lower possible league when their first team gets reputable enough?

Thanks in advance for answering.
