The best and most successful Scandinavian coach ever faced partly the same problem. Fantastic attacking side that some times exposed themselves too much and let in some easy goals. Once after a game they won 4-3 he was later in the week confronted by a journo who asked if they had been working on the areas that made them concede 3 goals in the weekend. His reply was classy:
"No. That game is still 4-3 if I am not mistaken".
People worry too much about things. We are constantly improving, establishing us as one of the teams to really fear. A little like the season we came second. Teams are worried prior meeting Liverpool. Let them try to attack our weeknesses and we will gung ho them!
We've been here before under both Evans and Rodgers in recent history. Rafa managed to get the balance largely right in that season with Torres and Gerrard.
You finish first by winning games though, and you do that by scoring more than the opposition. Heavy metal football right?
It's significant that we have made our best start to the league (goal scoring wise) since just after the dawn of man and also that we are the highest scoring team in the league since Klopp took over. The mixture of the squad and Klopp's methods has made us the most potent attack in the league and goals win games.
I'm not concerned about conceding a goal at Hull when we were already well up, or even the goal against Leicester at 2-0 because of the way we responded. I would be concerned though if all our games had been really tight affairs.
