Liverpool medical chief Andy Massey concedes Jurgen Klopp’s training demands did cause injury problems in his first two seasons in charge.
However, Massey insists the players’ bodies are now capable of handling the intensity Klopp demands.
“I always say that the manager is the most important person at the club and everyone else has to fit around his philosophy,” Massey said.
“Jurgen’s philosophy is very much that we’ve got to run further, run faster, run quicker than every other team because if we can do that then the skill will take over.
“So we’ve got to put the players in a position where they can do that. When Jurgen first came into the club, we tried to put that in there but the boys weren’t up to that physical level yet to meet the demands.
“At one stage, we had 13 hamstring injuries but now, with the benefit of two pre-seasons, we’re seeing the boys work so much harder and they look like they’re more protected.”
