I think more than a separation of two teams from the pack, we may be witnessing a much more significant sea change in world football, where teams who focus on building a relatively young team and keeping players together on those teams, rise to the top and stay there.
It doesn't negate good transfers of course, but it might reduce the emphasis on just buying, buying, buying on a yearly basis. It's visionary and would take the kind of ownership-manager relationship that we have. It would take enlightened club management to focus on player and team development along with match tactics (already important).
The top tier of world football has gotten away from this for a while, especially as the money from transfers has gotten so silly. IN a system where agents can persuade so much to happen, and their main way of making money is from transfers, it stands to reason that longevity at clubs is actually an enemy to these agents' interest and so, they work against it, paying players and managers percentages as part of the process.
But competing at a high level surely is enhanced by players staying together for longer. Klopp has chosen to pursue it this way and it is working. Many owners are going to like it, especially after the two-highest profile transfers of late, Neymar to PSG and Coutinho to Barcelona, are turning out to be way overpriced in turns of value for those clubs (along with numerous transfer fees of lesser value for players who just never return the value).
Agents and some players and managers will fight this trend of course, but as Klopp and Liverpool (and FSG) keep enjoying success, I can see more clubs trying to adopt the strategy long-term. It will take patience and people who really understand how to build teams, but it could change a lot, including the traditional balance of power in the top leagues (including England).
