Jurgen Klopp "doesn't look happy with football", according to Mark Lawrenson, who says the Liverpool boss has been adversely affected by the controversy surrounding VAR and substitutions.
Klopp has not been the same passionate, animated figure on the touchline of previous years at the start of the 2020-21 campaign, with fist pumps and cheers replaced by finger-pointing and angry outbursts.
Liverpool have been on the end of several contentious refereeing decisions which have prompted the German head coach to question whether video technology is a good addition to the game, while a mounting injury crisis has forced him to stretch his squad to the limit.
