Harry Kewell's agent has criticised Liverpool's medical staff for their handling of the Australian.
Kewell left Anfield for Galatasary in the summer of 2008 after a disappointing five-year spell which was blighted by injuries.
His agent Bernie Mandic told the Sydney Morning Herald: "He lost three-and-a-half years of his career at Liverpool because the guys over there in England had, quite literally, no idea what they were talking about.
"You have to wonder what they're doing over there. Perhaps they're trying to protect their reputations, but they're certainly not trying to protect their players.
"I think it's a disgrace, as I think it was a disgrace the way Harry was treated."
Kewell is currently undergoing treatment in his homeland for a groin problem but Mandic claimed Benitez had even asked the player about his treatment in light of on-going concerns about Torres' fitness.
"We had Rafa Benitez call him the other night enquiring who these guys were because Fernando Torres has got such major problems now," claimed the Australian.
Mandic's attack is unlikely to carry much weight inside Liverpool's Melwood training complex, where the medical staff have been credited with returning summer signing Alberto Aquilani to full fitness from an ankle injury after he was critical of his treatment in Italy.
