Liverpool are inherently an incredibly fair team, winning the fair play awards season after season. For better or for worse, our players don't go down even if there is contact in the box, because they choose to attack the ball anyway. Just yesterday with Mané from the left having a partial 1:1 with the goalkeeper, I am 100% sure that other players in the same situation would not have tried to take a shot, but take the ball inside a bit to force contact with the defender and go down to "win" a penalty. There's countless instances of this behaviour from our players over the whole season. Klopp would never encourage his players to go down easily, it's not what he likes to see in football. In some ways, we do suffer from that.
Anybody remember the CL quarters at City when Salah scored our pivotal away goal? Mané was fouled about three seperate times right before that goal and he could have gone down every single time but chose to keep going until he finally was forcibly brought down. I can guarantee you if Salah would not have scored that one, we would not have gotten a penalty for all the fouls on Mané.
