I'm sure they'd love a trophy. But they won't do what it takes to give the club the best possible chance of doing it. Not if it means eating into their margin a little.
They can non-figuratively spare no expense on the stadium, but won't on the squad. One is good for their investment. One is good for us as fans. One is a longer term benefit to the club, one is a shorter term boost where the asset will depreciate. But it absolutely isn't about safe guarding the financial future of the club. If they wanted to, they could chuck a bit more cash in, now and then. But they won't. It isn't worth it to them.
In what way do you think the 'asset depreciates' with investment in the squad? Afaia they don't take money out of the club, other than wages, so I'm interested to hear how their 'margins' would be effected as the value of the club is where their future profit lays - not in the operating profits of the club year on year.
