I've stopped worrying about the finances, because the sums involved are ludicrous and as fans we can't have any influence on what the club does/doesn't spend, and how the club spends, so it seems kinda pointless getting to worked up about it.
We were along for the ride when David Moyes was having to sell to reinvest, and we're along for the ride when we spent £45m on an Icelandic apparition.
If Moshiri wants to keep lashing money at it, so be it, just need his quality of decision making to improve.
