I think tan would spend some money if the circumstances were right to mount a serious challenge.
they aren't right currently, it would be a huge gamble to throw cash at it today.
our recruitment is hit and miss
there are no youngsters coming through
our squad is ageing and many contracts are running down
we might be hit with a transfer ban

if we get into a position where the above points are addressed, then we can think about investing significant money with a realistic chance of it getting us up.
