Liverpool will never challenge for anything with that defense. Klopp really need a plan B when things aren't going right. To be honest I'd rather we have a defense minded manager like Simeone. The guy knows how to set up a defense.
I used to think Koop was a good dude but he's just as myopic as any other manager. If the tables were turned and his keeper was on the end of that challenge he'd be going ballistic. Embarrassing interview.
