Klopp's clearly adopted a tougher attitude this pre-season. So far he's mentioned what Robertson needs to improve at, he's criticised Gomez for bulking up too much, he's criticised Grujic for his lack of self-control and his need to become more mature, and he's tended to focus on flaws in his post-match pressers. All of which suggests a welcome sense that a line has been drawn and higher standards are now demanded.
