That is a bit of an extreme end of a take on the point he made.
From what I myself have seen, without truly dwelling on it, there have been a couple big deals that were nowhere near their true value. They make up a chunk of that difference. Some to clubs in china, some in russia, and while that looks dodgy, hard to argue that those leagues do need to pay more to attract players there.
For the most of it though, Chelsea bring in a hell of a lot of young talent, that never gets anywhere near their first team, and gets sold for small profit a couple years on loan later. At one point, i remember noticing they had over 35 players out on loan. The profits o these arent huge, but that many of them year in year out, adds up, and thats where I would say their big income noted comes in at. And yes, nothing dodgy about that.
I guess we have been doing something similar, and it has been working to a lesser extent. The issue there being we more often end up loaning the players to sister clubs that don't use them as much and don't see their value and demand increase.
