Liverpool/Klopp is recieving criticism about the lack of spending, after last year's spending spree. But FSG business strategy is completely different from that of (for example) Manchester City.
Like he said, it's not really criticism, is just stating a fact.
City Football Group use Manchester City to spear head a long term strategy for global domination, and their business strategy go beyond Manchester City. They see no problem investing large amount of money now, with the potential of a much higher reward in the future. FSG is using a different strategy with much less risk taking and no other ambition than to make the individual company (Liverpool FC) grow.
What I would take offense to, if I was a City fan, is to be grouped together with PSG. PSG is a really strange project while City Football Group are on target to achieving their very ambitious goals.
