Jesus Christ. The end of Benitez's era sent the club back years - the entire club and everything that had been built was ripped up and torn apart. We've spent the years after trying to rebuild but for the first time, thanks to Klopp, we appear to be building with somekind of foundation in place. Unlike other managers, Klopp hasn't spent hundreds of millions looking for short term fixes and despite that, despite having a threadbare squad, we're challenging with these sides that massively outspent us and were starting from a stronger position too.
I'm honestly not sure what to make of your first sentence - managers find it harder in a more competitive league? That's pretty obvious, isn't it?
