The 34-year-old scored his 200th goal for the Blues in last month's win over West Ham United, taking him to within two of Bobby Tambling's club record.
"I have to consider all the squad, the main thing is the team," Benitez said. "Obviously I would like to see Frank break the record, but if I pick him it's because he's a good player.
"I think he can score goals and hopefully he can score more than two and break the record. Then he will be happy, we will be happy and hopefully it means we can win more games."
