When Jurgen Klopp isn't happy he'll soon let you know. The shouts, the pointing and scuffs of the turf in front of him reflected just how frustrated he was watching his side.
Yes, the result was a positive outcome, as it puts them above Manchester City, if only for a few hours, but this wasn't a defensive performance to be proud of, particularly in the first half.
All it takes is for one of Liverpool's four defenders to fall out of line or lose their discipline and the opposition have a chance.
Against Bournemouth they got away with it, but on Tuesday night against Napoli, where keeping a clean sheet is crucial, they may not be so lucky.
