All very good points - however those costs that have seen us make very small profit surely include our expenditure on player transfers which has been £100m + for at least the last 3 consecutive seasons (maybe more this is off the top of my head). This suggests that we are going to be spending the money anyway. We could for instance spend nothing on player transfers next season and make £150m profit?
Additionally, as I said in OP - neither Woodward or the Glazers are likely to spend any money on anything that could be described as 'Madness'. There are a fair few sticks with which to beat old Ed, but surely you trust him to not run us into the ground financially?
Point 1: It's key to look at cash again. The way deals are structured makes it kind of hard (e.g. Ronaldo fee was upfront, many other deals go across multiple years) but keeping it simple, the last few years have gone:
10/11: Spent 27m, Sold 14m, Net 13m
11/12: Spent 53m, Sold 15m, Net 38m
12/13: Spent 63m, Sold 12m, Net 51m
13/14: Spent 68m, Sold 1m, Net 67m
14/15: Spent 145m, Sold 41m, Net 104m (Obviously this is the execeptional, post-Fergie panic)
15/16: Spent 103m, Sold 75m, Net 28m
16/17: Spent 60m so far, Sold 0m, Net?
Key being the net values. We average under 50m net a season, with the obvious outlier of the Di Maria summer. That's still a huge net spend on transfers - more than any other non-sugar daddy club in the league. Ie, it's still loads.
This summer we've already spent 60m ish, and a 100m on top...we'd need some enormous sales to do it imo.
To Point 2: Do I trust Ed not to run us into the ground? Absolutely not. His biggest spending summer got us nowhere in the league, and his inability to make a call on LVG is costing us around 30m a season again this upcoming year.
