The only reason I mentioned the change of league was that this seems to have been the reason (or excuse) for last seasons squad to decamp as they weren’t able to commit to the extra travelling involved.I'm not sure the switch of leagues made much difference. They were taken over by mysterious new owners at the end of last season who proclaimed the usual ambition of aiming for the Football League, they appointed a Spanish manager whose only previous experience of English football was at Biggleswade United, so two levels lower and not even the same locality, he signed a load of players no one had heard of, unsurprisingly made a poor start and was gone soon after. There were issues with the ground and facilities and at one point they didn't have the use of the clubhouse on matchdays. Basically their season has been a shambles on and off the pitch, they wouldn't have survived in the Isthmian Premier under the circumstances, and now they're back in the Isthmian in the South Central Division along with Tooting.
As you say, their season has been a shambles and from what I understand, it’s far from clear whether they will continue next season. Hopefully that won’t be the case and they will survive in some shape or form.
