The great thing about Klopp's philosophy and tactics is that they only require athletic players with a brain. They don't need top level skills (although he wouldn't turn that down!) to play a significant part in the process. This is different to the Rodgers way, which really does need athleticism, speed, a brain, and top-notch 1v1 skills, no matter what position you play, in order to be truly effective. For Klopp, the 1v1 stuff only has to happen in the front three, and 1 or 2 players behind those. The rest just have to be smart athletes. Smarthletes.
Basically, Klopp can go out and sign a load of Dirk Kuyts, and it would work.
So in other words, while not signing top 1v1 players in all positions was the death knell for Brendan (especially as they are so damned hard to find without having a bottomless pit of cash), for Klopp, basic football intelligence and a huge capacity for workrate is all that you really need to be successful in his system. And that opens up a world of transfer options for us in the future, and means he can have a higher hit-rate than Brendan did.
And it's not coaching that gets managers fired, for the most part. It's transfers.
And it's not managers who win games, it's players.
So the future is bright. It's not perfect, but we stand a better chance as soon as the athletes with lower football intelligence in the team are replaced with athletes with higher football intelligence. That's easier to achieve than having to find a Cruyff for every position, including goal.
