At the moment, we will definitely struggle. We have a half decent starting XI as shown for most of last season, but injuries and suspensions will impact on us badly (as they would do on any part time team). A midfield general to replace Cav, a 3rd striker and a utility defender are urgently needed, but there is plenty of time and there are plenty of players. I'm pretty sure the management are doing everything they can to bring players to Alty, but it can't be that easy given our status.
As for the other teams. It does look a bit ominous for Torquay and Kiddy, but I'm sure they'll find a way of pulling through. I don't think Southport will be as bad as last season - they've completely revamped their team and will be less dependent on loan players. Guiseley didn't look that great in the play off final, but they play a very similar style to us and I have a feeling they'll be okay in the national division. Aldershot were bog awful last season, but they too have completely revamped their squad, so it is difficult to tell if they will struggle again.
In short, I think the standard in the league will be higher next season, so the calibre of the three players or so we bring in will be critical to our chances of survival.
