If what Blatter said stands (and he's the president of FIFA so why wouldn't it?) then we're safe in the A-League. The only thing that Hammam can do now is try to pressure the FFA into siding with him, and that doesn't seem likely.
In terms of the ACL, I don't think we will be able to qualify since that would be governed by the Asian Federation (and Hammam has it in for us). I would love to be in that competition but if its not possible we should at least be able to play in the club world cup, should we qualify.
Don't forget that whilst Blatter is FIFA president, it is not as simple as what he says goes. The FIFA statutes are quite clear on how issues get decided and it is not a case of "President decides" - just as it is with the US president, UK PM or NZ PM. They get a good deal of input and can call on supporters to vote accordingly, but they can lose on voting issues too..
Having said that, I don't think our survival is in question per se. The key (question number 1) is whether we must conform to the three imports-only rule with NZers counting as imports. Hammam already said he wouldn't oppose our presence on that basis. The key question (number 2) for us is whether observing such a rule would threaten our support base sufficiently to cause us to fold.
Ultimately, it's up to the FFA about the A-League and the AFC about the ACL. If the FFA want the AFC to award more ACL spots, they may decided to support Hammam. If the FFA aren't worried about getting the AFC to cooperate with the desire for more spots, we should be fine. So which is more important to the FFA is the key question (number 3).
And has been observed, no ACL means no Club World Cup. Just as no ECL means no Club World Cup for European teams.
WellyPhFan - we are not an OFC club, so the O-League route is closed - as confirmed by Tony P on about page 1 of this thread.
