Yes pretty much. I think they've looked at it and can see they cannot sustain Liverpool trophy winning team. In all honesty, it's probably a sensible ploy. They've maximised revenue effectively, been good in the transfer market etc. They are very smart people.
There are 2 options for Liverpool here from what I can see. Either a quick sale (which would be good for them) and the new owners will be in place for the summer. The other one, is it's the start of a process. This would be less positive, as it can tend to drag on, and an inertia can set in. If I'm honest, I think we are in that phase now, and you can see the impact it has.
Forget about signing players like Bellingham, nobody does that if they are engaging in a sale. Often the interested party will sign terms that give them protections, and one may be that transfer activity is vetoed (again a little bit like Chelsea had during the process to buy their club). Chelsea's went through very quickly for political reasons of course.
The most likely outcome will be another American firm, maybe a fund coming in. For whatever reason, American's seem to like the PL currently, which makes Henry's decision interesting. While the super league is obviously completely unviable from a commercial perspective (and always was) there does seem to be inclinations that other things will change (could easily see a world where no relegation for founder members of the PL come in etc) to give some stability. So within that context for Henry to walk away is interesting.
But then again, it's not. He is quite mechanical about it, and will know tha 2-3bn for Liverpool is massively over value, and he can get a better return elsewhere, without the ned to have to keep funding them.
