However, the Reds boss welcomes the dilemma and hopes the situation will see his side hit the back of the net more frequently than last term.
"For me it's a good problem, " Benitez said.
"I like to have these options up front. We have different options now and it depends on the game but I think all of them can play together and that is the important thing.
"It depends on the game. If we want to play more crosses, Crouch can play or Voronin, and if we want to change the game we can introduce a different striker.
"I think last season the team was attacking but I would like to see more goals.
"We were attacking a lot but we can now improve the accuracy and hopefully we will see more goals."
