Speaking of Santiago, wasn't there a rumour(?) that she wants to naturalise. Is that still happening?
Was it a rumor or just wishful tweeting? I remember seeing a few people here say it would be a good idea for Japan. She's a gift. I can't remember if there was some unhappiness from PHI folks about the idea or if they thought it would be cool
Regarding Santiago, it was actually her who mentioned in her interviews in the Philippines that she got an offer for naturalization from her club (not JVA), so that she can play as local. She did not turn down the idea and mentioned that she is thinking about it.
I'm unsure what the process and requirements are for playing local in vleague, but if she wants to also play in the NT, it will be much more complicated and would need a few years of residency considering also that she played for NT of another country. She's turning 26 now, so if they want to decide on these things, they might want to start with the process already.
