Or maybe, as lots of different places have now suggested, Klopp really does only want to tweak his squad with a side player here or there?
Klopp strikes me as a loyal kind of guy, much like Wenger. It's why their players love them. But that lack of ruthlessness ala Ferguson, Guardiola or Mourinho, is why, at least in Wenger's case, he never managed to dominate in the way he should have.
This is exactly the summer Liverpool should be spending big. The money's there, they'll never be more popular, and the big teams, for the time being, are nowhere. A Pepe and a Koulibaly, and they can afford that by all accounts, and they'd win both major trophies next season.
