Past experience - like Spurs last years - is that a team can run out of steam if it plays at a high tempo and there was some evidence with us last season. The difference is that we have had a full pre-season and we have more strength in depth with players all trained to play the same way.
Just compare this years squad with last year and you see how much stronger the squad is...
... Not necessarily numbers-wise, but just stronger (with the additions of Karius, Matip, Klavan, Wijnaldum, and Mané), along with the emergence of youngsters like Ejaria, Grujic, Trent, Ojo, etc. Overall there just seems to be more quality and a much more stream-lined collection of players.
It's also a big bonus to have found a good role for Milner who has shored up the LB slot.

Looking long-term it'll be interesting to see how highly regarded Wilson, Kent, Ojo, and Woodburn are, as the only position the first team isn't well-stocked with is wingers - as Klopp himself said just last week:
"It’s not about how many strikers. Three strikers is enough, I think. But
when Sadio is away we will be without a winger.
We do not have many wingers, I would say. Roberto Firmino could play as a kind of a winger which would then just give us two strikers. That’s how it is."
Other than that, it's a strong team with excellent options off the bench.
