A couple of thoughts:
Liverpool will eventually achieve a stabilized profit level and at that point they will redirect funds into new ventures. Given the large number of long term contracts recently extended to the sizable group of core players, I foresee more controlled spending in the next several years allowing FSG to achieve a higher level of profitability.
What are the rules about buying teams in other leagues?
I suspect ownership views the EPL and all of European football as a sports business still in its formative years despite the sports' long history. If they view Liverpool as every sports owner in the US views their sports franchises, FSG will never sell until the estate planning phase. Baseball, football, basketball valuations only go up and up and up. They are legacy investments that offer prestige as well. Partners may sell their shares but FSG will never unload a legacy investment.
Interesting points, but "stable profit" is not a given in football.
Failure to qualify for Champions League, changes of manager, turnover of playing staff and many other things can see a club sink quite quickly.
Look at Arsenal for example, big earners, a champions league regular, new stadium all paid for, and yet they are struggling at the moment, compared to their peak years.
FSG also cite TV revenues as a risk factor in the annual report; no one knows if or when the bubble will burst with the huge amounts of TV money on offer, but burst it most assuredly will, sooner or later (my guess is later).
If we're talking really long term (10-15 years) then I would expect Mike Gordon to take more control at LFC.
He's another interesting character, and stays very much out of the public eye.
However, since his buy-in (now the 2nd largest FSG stockholder after Henry), the club has been much more pro-active.
Perhaps JH wanted to take a step back at his age, and we know he concentrates exclusively on the Red Sox these days, while Gordon runs Liverpool, although the group is run in a collegiate manner.
Interesting times ahead, and hopefully successful ones.
A decent year in the transfer market, this year, and last summer to be fair, so the signs are good, but football is a very unpredictable sport, and you never know what's round the corner.
