Liverpool striker Peter Crouch has been told he will have to settle for a supersub's role this season.
Benitez refused to accept that Crouch had made the difference and reflected the 26-year-old may have to become used to life as a substitute.
"Maybe that's right," said Benitez, when the point was put to him. "Some players are like that.
"Some players, when they play for 20 minutes, are more important for the team that way.
"We did better towards the end but perhaps there were three reasons.
"Harry Kewell was on, Blackburn were getting tired and then there was Crouch, too. So there were three things together."
