Thing is, you could feel the 1-1 goal coming for Everton because it's the karma that happens anytime a team that looks in control with 1-0 who fails to secure the win with the second goal. Klopp can blame the ref but I think in reality, the two main mistakes was Mané right before half time when he didn't pass the ball to Salah/Ox (easy 2-0 there) and then Lovren for being clumsy. Say what you want about the penalty being very soft, but as a defender you shouldn't give him the chance to fall flat there. Whether it was a push or not, just don't give him the chance.
