DiabyKungFu Look at early-stage venture capital here. How it works (almost without any exaggeration) is that a VC takes a look at the cofounders' resumes and other funds that have committed money and if they see enough brand names that they like then they write a check for many millions of dollars. Otherwise, they pass. The idea that higher leverage situations necessarily call for more complex strategies is a fallacy. It is usually the opposite.
But ... don't you think those conditions are very, very dissimilar to trying to negotiate with one of a small handful of footballers who are likely to improve an existing elite squad, all in the context of PSR, competing clubs, the player's existing contracts, etc?
