A solid defence could be just making the team not have to force things quite so much.
Like they will know a 2-0 lead means that the game is over, that they can likely hold a 1-0 lead while loking to score another rather than chasing it becuase they feel they have to.
As a factor in there somewhere, for the home games say, they become more like routine victories.
Thing is though, the free-scoring mob were also drawing games through mysteriously not scoring at times (those home draws) - so that's been got rid of too, it would seem, pre dating the proper orgy of goals maybe, that might have been, I don't follow so closely to have the exact details on recall.
Bigfoot Klopp might be trying to conserve energy for later in the season if it's a conscious tactical thing.
I wish it would stop anyway,
. VVD's ribs must be getting really sore, all these injections. And doesn't Moreno need a runout just in case he's needed** for a crunch game at some stage.
**no alternative can be found anywhere
