If Scotland vote no to independents will there be a team GB in the next cup.

No. All the Home Nations compete in their own right as separate members of FIFA. This is one area the FA's will fight to preserve, which is why the GB Olympic team featured mostly English players. The Scottish vote would make no difference to football

I really can't see the fans taking to it either to be honest - there's been far too many decades of wanting the other teams to fail to just put it all to one side and get behind a unified team.

No, because it would mean nothing changes. They'd be choosing not to leave rather than choosing to join.

We (England) don't need Scotland, we need Wales.
